Use prefabs/blueprints in UE4 to SAVE TIME! | ArtStation Challenge EP.004

In this video I give a quick update on the status of the scene and also go over one of the biggest ways I save time during environment production. I can't recommend using prefabs and blueprints in unreal enough!

[@EpicErrorjack]

Instead of just prefabs, if the structure is pretty uniform and majority of the same material, you can merge them to reduce a ton of draw calls. You won't be able to remodify them but you'll gain ton of performance. But if you do use the blueprints, make sure it doesn't tick to save CPU performance since those will be running every frame even if there is no code running in it.

[@PolygonAcademy]

yea good point on that no tick! for personal work it's not a huge deal but for actual gamedev it sure is :)

[@hemingway8671]

I rewatched your entire series because I'm starting a new project both at work and at home and I'm still learning new stuff form your videos ahaha! I use ue4 but I didnt make a habit of creating blueprint for assets. God it's going to save me some time. You've help so much with my production time. It must be an awesome experience working in studio with you. Thanks once again!

[@PolygonAcademy]

thanks so much! I am happy to hear the content is worth a re-watch :D appreciate the love!

[@design_and_decor]

Its me, I am the player that not only notices but greatly appreciates all the individually placed grasses, foliage and assets in games. But that prefab ability is amazing as well, a mix of the two would be *chefs kiss*

[@PolygonAcademy]

yea for sure :) using prefabs to get the overall base in place quickly is great for building momentum and then creating variations you can swap out or doing some more custom hand dressing during a polish pass if there is time (especially during production post alpha) is the way to go :) thanks for watching!

[@dandymcgee]

This is absolutely incredible. I'm a programmer, not an artist, but I love watching and listening to your in-depth explanations of your processes because it helps me think about how to create tools and organize data in a way that best enables these types of highly efficient workflows.

[@Sean_Dennis]

you can also use the construction script in the blueprint and create a spline mesh component. So you can have a mesh at the start of the mesh and other at the end. Then once placed in the world you can then drag the spline and create wall, fences. Also you can add a random seed to randomly place the blocks on top at different heights.

[@PolygonAcademy]

Sean Dennis awesome tip, ill have to try it out!

[@MZONE3D]

Nice quality videos mate. Some nice tips for those beginners.

[@PolygonAcademy]

thanks! that's the goal :)

[@moutrave]

In my last scene I used bluprint with enumerations so I could swap the deco mesh that would be place on top of, say, a wall or a floor. So i made a base wall, and each time I'd create a new trim to put on top, I'd add it to enum and expose it so in the editor I just have to select with deco I want from a drop down list. I think I'll keep using it for all my next projects actually :p Another time I randomized the placement and orientation of flower on a surface and put it in a BP, so when you instance it, it always looks different without changing the mesh location. Anyway, thanks for the cool videos :)

[@PolygonAcademy]

Clémence Maurer awesome, both of those are super useful sounding ways of using blueprints 👍

[@MF-mn4vx]

Not only that you can use instanced mesh for optimization even add the broken peace(for the tiles) at random by looping through the group of meshes and some logic in the blueprint, even present logic for the different instances so some can have random rotation in range and other tile group don`t. Great tips.

@@PolygonAcademy I have seen people willing to help and share their techniques so that we can all grow as a community, but they all pretty much say the same things, or how to achieve some effects or how to model something. Nobody gives an insight and workflows to further help people speed up or who want to break in the industry on their own. Take an example of me, i am alone having no connections and no mentor,i don't have anyone remotely related to 3d, just polycount, so there was little to no chance i could ever find something like this so thank you and keep doing what you do :)

[@trekull-]

I feel like the tips you give will become more and more valuable the more time I spend level designing. Maybe I'll show the level I build following your tutorials when it's done! Anyway, thanks for your time and effort

[@PolygonAcademy]

thanks! definitely drop a link to your level when its done here in the comments, i'll take a look :)

[@trekull-]

@@PolygonAcademy Hey, I wanted to ask your advise on time investment. I'm diving into game development and level design seems the most fun for me. Should I focus on designing in Unreal using assets from marketplace or learn 3d modeling for creating assets. Or should I balance my studies in both?

[@PolygonAcademy]

Denys Mamonov if you want to do level design, you dont need to model. Use market place assets and also show some simple greybox work with some nice lighting, that always looks cool. Focus on showing and communicating gameplay spaces and flow through a level. Like have a top down map that shows combat spaces and traversal areas etc.

[@trekull-]

@@PolygonAcademy Really? I thought that having the ability to make my own assets would make me more hireable. I still want to give Blender a look, maybe I will enjoy making 3d. However it is nice to hear that you can live without 3d modeling. Is it possible to contact you outside of KZbin comments? Maybe discord or smth. If you want to, of course

[@PolygonAcademy]

Denys Mamonov yea it wont hurt to learn asset creation, especially if you have never tried it much, you might really like it :) but in general level designers are more focused on layout/gameplay, while the artists are making the assets, so just figure out what part of the process you enjoy more by trying both out :) you can hit me up on artstation or instagram dms, i dont use discord that often.

First of all, AWESOME videos. I learned a ton from them. I started doing a personal scene project and after watching your videos I learned I was doing EVERYTHING wrong :D. Basically I started from the back to front with creating models and stuff. But, that is not importnat. I have a small suggestion, which may be beneficial for us newbies to learn better. You could use some of the softwares that provide what buttons you are pressing, so that it is easier for us to know what you are actually doing :) And again great content and I am waiting impatiently for more :D

[@PolygonAcademy]

thanks for the in depth feedback Vasil :) really appreciate it. i will look into the button press software and see what I can come up with!

Prefabs you say. Do I sniff a Unity series? ;) Thanks for the videos man, you are a legend!

[@alanandrade9056]

This is awesome! I have one question though: the materials that you use are procedural (so you can reuse on different meshes) or do you have a single material for every single mesh in your environment? Thank you and keep making videos like that :)

[@PolygonAcademy]

cheers! about half the materials in this scene are tiling textures and then things like the bricks and tiles are unique unwraps/sculpts. so a lot of the meshes have a shared material for the moss etc.

[@PerFeldvoss]

Nice but you should take a look at the (free) Prefabricator that will even help you set up randomness (yaw/scale) and other cool stuff.

Hello! just want to say the videos you put out are amazing and honestly ive learned more here than any other channel especially when it comes to seeing the fuller picture when it comes to workflows and pipelines that are all explained in a easy way to understand. Im afairly new subscriber and was wondering if this channel is going to start uploading again because all the videos i see on the channel are from a few years ago. Just curious is all. thank you for all the knowledge you have put out there!

[@PolygonAcademy]

thanks for watching! hopefully will resurrect the channel at the end of my current game production I am working on for my studio day job once I have more free time :) appreciate the sub!

[@seansopata5121]

For some of the meshes in the prefab, I'd throw in a random bool function to enable or disable visibility. So, for example, not all blocks get the same amount of grass. Or at least add the ability to manually control them on a per instance basis. At least, that's the route I've taken. It really only became a performance issue in really really large levels.

[@PolygonAcademy]

yea thats a cool idea, players would never notice slightly different grass layouts while running around, but for larger modular prefabs like shrines or statues that would be quick and easy to add large scale variation. good suggestion!

[@MaximumHorizons]

WOW, why other "masters" of unreal dont say about this feature, its so cool and easy! Thanks!

[@jihadsadi1575]

Your videos are the most helpful things I found while working on my own game , keep that great work dude. But can I ask what the texture that are you using , you now how it's changing when you move the object 😅

[@PolygonAcademy]

Jihad Sadi cheers! I am using a z-up shader that puts the moss procesurally on a mesh on any faces that poubt upwards, with a world aligned texture co-ordinates to have it work properly. Look up lincoln hughes prop shader, its the one i used.

[@dalittleberry]

Hey Tim I really love this video series! keep up the great work. Could you do a video on lighting. That has been something that I have always struggled with personally

[@alexandruachim743]

I agree, I've been struggling with proper lighting for so long. Also lighting at night or dark interiors is really tricky. Hope Tim covers it in a video one day =)

Yea I will dive into master materials in the texture/materials vlog coming up and probably make a longer tutorial on them as well. glad you are enjoying the content bud!

[@pixelissue]

I have a question: if you create a level like this in a separate Unreal scene, what are the steps to import everything, including the height map for the floor, into another scene such as a larger map?

[@PolygonAcademy]

easiest way would be to use the levels system inside unreal and have the smaller one you want to bring in be a sublevel of the overall master/world map.

[@Walkion]

Hi there ! Thank you for your videos man, its really interesting to get tips from people that good ! I was wondering if you would bother talking about your lighting setup in UE4 and what little tricks you can use to quickly define a nice light in your scene ? That would be super cool of you !!

[@DavitMasia]

After added in the prefab, if needed, is there any way to "unlink/ungroup" to get back the individual static mesh objects? . Also is there anyway to set Pivot at floor or similar, so when you place the object in the scene it does above surface?

[@adxmartistic5974]

Hey! Great video, using this for book stacking in my scene :) I need to make all my BP's static for the stacks to be seen in the game port? Is this normal?

[@alexandruachim743]

Hey Tim! another great helpful video =) I was wondering when I was watching the video, specifically at 13:00 you moved pieces around in the prefab mode and the texture on the brick changed as you moved it around, it wasn't the exact same when you duplicated the piece, what is going on? Thank you!

[@PolygonAcademy]

alex achim the moss on the top is being added procedurally with a z-up shader, and the moss texture is using world space uvs, not the meshes uvs, so it looks different when i move the meshes around, makes it easy to eliminated repetition ;) just look here on youtube for z up or moss shader and world space for some in depth technical videos. My buddy made the shader, and will probably put it up for sale soon ;) its super useful

[@cursenova]

Thanks for the great video :D Just a quick question, how do you break the Prefab files that you just created?

[@PolygonAcademy]

DanielH hmm good question, i think there used to be a way but i cant find it. You can actually move components inside that specific instance of a prefab uniquely just by selecting them in the details panel of that prefab, and it wont move all the rest, but breaking them back into individual meshes i cant find. I wouldnt recommend it generally, its better to make a variant with the changes you want. A scene full of old broken prefabs bit me in the ass on watchdogs 2 when it came time to fixing things :/

[@cursenova]

[@legendofpersia]

hey great video! how do you make it so that textures stay on fixed coordination? whats that sorcery called?!

[@PolygonAcademy]

behnam vahdati its using world space uvs, pretty simple, there are tutorials on youtube. Helps with seamless grunge maps or things like snow/moss.

[@KiwiHawk-downunder-nz]

Thanks a heap for these, I started very very late, played Elder Scrolls starting with Morrowind, now trying to build those world styles in UE4 to keep my ole brain working, I come across some choice Prefabs in Unity way way back that where rock forms with grass and mushrooms etc and they had a tree or bush in them, not sure this can be done with speedtree trees or trees with wind componats. the other thing I was thinking of is (and I'm not sure of best practice as yet) modeling or making a material that can be instanced with texture parms so that one could bang in different substance's to change the useage of the model, not sure mu 70 year ole logic has this right lol, for example I thought of changing the normals etc under your tiling trim to change it from rock to metal, cracks could become scratchs. Time to stop rambling, sorry.

[@PolygonAcademy]

yea totally, if you standardize the widths of your trims to things like 1m, 0.5m .25m etc you can easily swap surface materials and styles if you keep it all consistnent with the uvs, allowing for quick variation with a material swap :) good call!

[@jaiujjwal8674]

Ok I see a pattern here, molecularity and re-usability at every level of production. Like u make models and make assets, and then assets to make prefabs. Also question what if we need to edit just 1 of the prefabs, should we just copy and make it as a different one or like un-group the blueprint?

[@PolygonAcademy]

yea I would just duplicate and make a B version of the prefab. sometimes you can break them too but it makes going back to fix them an issue. better to just make prefab variations and swap them ;)

[@lz4090]

Great tutorial. Hi are the textures of your stone tiles using a world position? They seem be projected in the world position when you are moving them. May I know the rationale. Thank you

[@PolygonAcademy]

Yea the moss shader uses world position, so it gives a more organic result when you move the meshes around so you dont see the same moss pattern on every stone. Its also just projecting down on the z axis so you dont have to do another uv set for it

[@Lync1111]

Do you have a tutorial on how to get that video game controller working with the program on your computer, Thanks.

[@PolygonAcademy]

Vivek Kumar Ranjan when i build the blockout pieces in 3ds max i create a biped or sometimes just a 2m tall cube to act as a scale reference for a human size. Thats why blocking out simple shapes first before going super detailed is important, you test in the game and see if it feels right, and then add detail after :)

[@pawpotsRS]

question, for that unique asset like torii-niwa in making large scene do you recommend to sculpt it uniquely or rely on trims or seamless texture?

[@PolygonAcademy]

it really depends on the asset, but for focus piece/hero assets, its usually worth it to make them unique sculpts.

[@pawpotsRS]

​@@PolygonAcademy is the art direction will not compromise since in studio they have texture set where they will sent you a texture and from there start to make a mid-res poly ready for integration or yes right it is depend if worth it, I assume one is exceptional like character weapon, armor. thank you man! been re-watching this journey of yours many times :) btw for the last abusive question of mine, do you think or consider using Quixel Mixer in the future since in production speed is important and most studio's now doing photogrammetry and quixel asset is made from that. thank you again and please take care.

Hi, I used pretty much the same method to do blueprints but now there are few different settings when creating them. Could you tell us which options you choose once you are in the editor and click convert to prefab? Your video is a bit dated and skipped that part entirely. Also I'm about to stop using blueprints altogether since it's absolutely impossible to vertex paint on blueprints. Did you find any ways to solve the issue? It would be a game changer and it would help alto since I'm working on a very important project that uses blueprints alots Thanks so much!

[@zarkeven]

how do you make the light render in real time? ive been trying to do that forever but can never really manage to

[@PolygonAcademy]

set your lights to moveable in UE4, that makes them 100% dynamic.

[@Silen00]

Hey, great work, very helpful. I have a question though (slightly unrelated, but not sure if you're reading comments here anymore), I see on some of the brick wall pieces such as at 5:00 that there are bricks popping out and the silhouette of the model and the corners sort of matches them. I wonder how you've made that? The way I'd do it would be to simply model a cube, bevel the edges, unwrap it and slap a tiling texture on it. But how would I get those bricks to pop out and change the silhouette like you did? Cheers.

[@PolygonAcademy]

all the bricks on those wall meshes are individual models, not a tiling texture. there is lots of geo there exactly to pop those silhouettes like you noticed :) polygons are not that expensive these days, and with aggressive LOD's these walls stayed pretty performance friendly.

[@Silen00]

@@PolygonAcademy Thanks a lot for the reply! Sorry if I bug you with questions but I'm trying to learn since I'd like to create similar assets. What would be the workflow to get something like that done? Would you sculpt the brick wall in zbrush, then retopologize it and bake the normals? Or would you for example model every single brick individually in Max and then stack them to form the wall piece? Right now especially for very large stone walls I'm just using a simple model with tiling textures, and I'm not sure if that's 'correct' or the 'best' way of doing it. Hope these questions don't sound dumb. Cheers!

[@PolygonAcademy]

@@Silen00 on this one i think i sculpted and baked 3 unique bricks, and then just assembled them into modular wall pieces in max, scaling and rotating the 3 bricks to break it up a bit.

[@Silen00]

@@PolygonAcademy Great, thank you!

[@ghua]

could you show wired geo from time to time? I am not sure how dense are stones

I will try to remember to do so in future. the polygons were pretty dense for this scene but it small and enclosed, for a large open world scene it would be a bit more lowpoly for sure.

I'll be following on twitter shortly. thanks for the vids and giving me a better scope on what I should focus on. I keep trying to make a "video game" with no prevail because the scope is to big but now after watching your videos I feel like id have better time and learning and gaining experience with just doing scene and different themes. thanks after being away from ue4 & maya for 6 months you gave me that drive to create! ever thought about making a subreddit r/polygonacademy and every friday or something giving the subscribers a theme idea in a video and in a week we post it on said reddit? I feel it would be a nice way to inspire viewers.

[@PolygonAcademy]

oh good idea about the subreddit, maybe one day when I have more time! yea the floor is a combo of rock meshes and also a landscape mesh made with unreal's terrain tools.

[@DPDPDPDP]

Oh man its like revelation

[@PolygonAcademy]

yes! thats what I like to hear :D glad the video was useful :)

[@brainshack9077]

Even though using BPs for this works, I feel like it is kind of limited. Especially when you want to modify them in Scene View. Other engines do it better imho. Fortunately, there are plugins on the market place that enhance this Workflow, like Prefabricator, which sort of immitates unity's prefab workflow.

[@PolygonAcademy]

yea this is pretty much the most basic version of the process, prefabricator seems extremely promising for sure :)

[@MJBJK]

well i see blueprints more like scripts, since you can apply logic to it or creat BluePrints out of CPP code. So kinda had hoped that you have something other as a Prefab mechanic, but well can't have it all but never forgett to de-check "Start with Tick Enabled" otherwise it will generate Tick-Events and that will slow performance down even if it doesn't do anything and is only a collection of Static Meshes

[@PolygonAcademy]

yea good call, we actually just had to deal with that exact issue at work, I wasnt familiar with that before haha. hey, im an artist, not a tech artist ;) haha thanks for the info!

[@MJBJK]

​@@PolygonAcademy You're Welcome, well even a programmer that started learning the Unreal Engine can easily miss it, in my opinion the "Start with Tick Enabled" checkbox shouldn't be enabled by default since you only want to have it enabled when you actually are using the tick event. Also i found out that there is another way. If you select Multiple Actors in the Level Editor you can Right Click and there should be a "Merge Actors" which will open a dialog to creat a new Static Mesh Actor with the selected Actors in their current position, you can convert it to a blueprint afterwards but i don't think you can change the relativ transform of one actor since it treats them all as it they were one instead of when creating a blueprint out of a selection it will add every actor as its own component which allows you to reposition or change one single part of the selection. Haven't looked too much into it since i already used blueprints as prefabs and the group functionality.

[@PolygonAcademy]

@@MJBJK yea here at the studio after we found out that tick problem we changed the engine code so its off by default, was a quick insta fix for some performance gains.

[@gian-227]

Thanks for the video but if do that with my door, door-frames and walls, the c++ component used for opening the door doesnt work anymore: do you have a quick solution? Thanks man.

[@PolygonAcademy]

on most games ive worked on, openable doors tend to be their own seperate blueprints and not included in building prefabs, usually its the level designers who are placing those elements within the world. I would try and keep it as a self contained blueprint per door/button that opens it etc. there are probably ways of having the c++ components interact with specific actors within the blueprint, or just script the functionality within the blueprint itself via nodes.

[@gian-227]

@@PolygonAcademy thanks a lot for the really fast answer, thank you for what you do. Bye.

[@PolygonAcademy]

@@gian-227 you're welcome! cheers

[@howl13]

so freefab is equals to master material?

[@PolygonAcademy]

Similar kind of idea :)

[@turalmemmedov3648]

I just realised your awesome videos about UE4. Lighting academy, dinusty and this is top 1 tutorials. And I have a question about your scene (may be this is dumb question). I see you are using world align textures, and I can see even dinusty using it. I searched and I found it is performance heavy. So how often do you recommend world aligned textures? For example, Can we use masks as world aligned textures to blend tiling materials on large scale without vertex painting? Or it is not good idea, because we have to use many masks? Hope I could explain my question )))

[@PolygonAcademy]

Tural Memmedov yup your question is great. Its a bit more expensive yea, but i know several big aaa games here in montreal that are using world space uvs for almost everything, they just find ways to offset the performance cost elsewhere, but in the grand scheme of things its nowhere near as costly as lighting and volumetric fog etc. Using it for masks to breakup dirt maps on buildings is a great way to use it too, makes everything look unique!

[@turalmemmedov3648]

@@PolygonAcademy Thank you very much. The people like you from industry is a big gift for us )) Last few years I have learned hard surface and tried character modelling a bit. Right now want to move to environment art and after that I want to decide which one I want to work mainly. :) This is my artstation and my two WIP models in polycount.

[@musicdudem6673]

So ive been dabbling in unreal for awhile, but once in awhile theres just things so basic, so common sense that i completely miss them. Ive been so dumb building everything by hand and recently thinking of my last projects issues and i just had to sit down and laugh my ass off. I dont smoke, but im pausing this video to bum a cigarette and rethink my life smh

[@PolygonAcademy]

Hahahaha 😂😂😂😂

[@jb_1558]

he shows how to actually do it at 10:33

[@IWillYeah]

Note however, having too many Uobjects, such as actor blueprints can kill performance. Replacing the current meshes by highlighting all meshes of the same type in the editor and then setting a new maeh for the selected seems like a far better solution for staic mesh that don't need extra functionality. Otherwise prefabs would be a better option (marketplace, free and paid).

[@PolygonAcademy]

yea for sure. the problem with the select and replace issue is that if the pivot was changed or different you will have big problems in your level. but yea, the prefab tools from the marketplace are a better solution.

[@user-dl7ct4ce5p]

Why don't objects show up when I'm running？

[@iiTzMythic]

Or just build the asset in the editor after building select all meshes rightclick and confert to staticmesh even faster and no BP needed that way is a real prefab so the same as in every engine so its not called differend youre just doing it differant

[@PolygonAcademy]

That works after you are sure the asset is locked, but a lot of times during production we are constantly changing or updating blueprints until past beta, after beta yea we tend to convert to sm and instance them all. If you convert to sm right away, you cant update the thousands of meshes used across multiple levels without replacing the baked down sm, its a time sink for production when using thousands of assets across multiple maps

[@iiTzMythic]

@@PolygonAcademy intresting i never had this problem youre recaling to of course the update as long as its the same SM or instant of that mesh because youre updating the master this will overright and update all the other masters or instants placed in the world

[@CptEddyPrice]

any free software for aspiring artists?

[@PolygonAcademy]

CptEddyPrice you can get a free educational license of 3ds max from autodesk, or blender for modelling, substance painter and designer are only 20 bucks a month, so with all that you should be covered, and unreal is free too ofcourse :)

[@westomopresto]

Having a shit ton of static meshes in a blueprint actor prevents you from being able to instance them. Creating a ton of drawcalls. Unlike Unity you cant break the blueprint down to its components again after you've combined it. It's a one-way road.
