Why Rendering your Blender Project in Unreal Engine 5 is a Game-Changer!

Instead of applying all modifiers, which in most cases is undesirable, you can check the "apply modifiers" on the export settings in order to apply them only on the exported fbx.

underrated comment with 600-IQ

[@Zoran_Zivic]

A few friendly suggestions that I wish I knew when started learning UE: - When using Bloom, if you have metallic materials select Convolution, not Standard effect like you did, it will look better. I always use convolution bloom because everything looks better, but it has a hit on performance. - Since you are working in 5.3 you should also set Max Bounces to more then 1(default value) in Postprocess/Lumen Reflections. This is very important if you have mirrors, or glossy surfaces. I usually use value from 3 or 4, depending on a scene, but you should also know this can have big hit on performance. Earlier versions did not have this option, and it is one of a major improvements in UE 5.3. - You got error message "Lighting needs to be rebuilt"... In your case it is because you were using Stationary or Static lights, and they need to be baked to be accurate(But baking lights is a hole different topic)... Change them to movable and problem will be solved, When using Lumen you do not need to bake lights, it can look awful if you did not unwrap second UV Channel properly in Blender, or did not check on import for UE to create new lightmap channel. Also when seeing red X on lights (like @7:08 light under the stairs), that means that you have more then 3 Static Lights overlapping in your scene, and they will not be calculated correctly, just change them to movable lights and problem is solved. - When creating materials, create parameters and always use instances. Material instances will apply and render material changes much faster then parent material.

Bro... Thanks a lot for writing down all your experiences and correcting what I forgot to explain or simply did wrong. Much love ❤️ and thx!

OMG--I just discovered convolution a few weeks ago! I mean what a game changer. And you don't get all that unwanted lens flare--just a nice, intense glow. I set the intensity really low to like 0.01 and crank up the scatter dispersion to 60...beautiful results.

So by the sounds of it, this is a very useful workflow.. but only if the rendering time decrease properly offsets all the time required to reconfigure your whole project inside unreal 5.

Eevee is getting a pretty big update soon, it should help with some of the issues you've seen. As for "why you should wait days" comment, it's simple: because it looks much better. Like it or not, rendering in Cycles or another similar renderer gives much better and accurate results. For simpler stuff UE5 is fine.

[@funnyberries4017]

yeah I hope a lot of his gripes will be fixed with eevee next. I usually optimize my scene and get about 30 seconds a frame. But yeah, a 5 min render is still 60 hours at that rate. The goal is to get good looking 5 second renders, so a 5 min render can cook overnight. i have a rtx 3060 and 16 gb of ram. I feel like I could get OP's hallway render under a min a frame with optimized cycles.

[@tylermansmann2843]

one could argue that ray tracing cycles is a superior renderer to Eevee. We use Eevee because it gets us 99% of the way there and adds some new tools as well and is 10x faster. So why not use unreal engine 5 in the same way? They have gotten the formula down for cinema ready visuals delivered in real time with innovations like nanite and lumen. Yes, eevee is rendering all millions polygons in a scene and nanite is only rendering 1/5th of that, but it's doing so intelligently and on a frame by frame basis. this doesnt mean that eevee is useless, far from it. but if you are trying to deliver high quality looks on a time budget, UE5 with Blender together is the new meta

[@haven_art]

Theres a version of blender with Eevee SSGI

[@bobsteven2363]

Eevee Next is based on ssgi which was already available in the past and present on blender (There are other improvements, but nothing that makes the renders look better imo). Meanwhile Unreal engine Lumen is based on actual raytracing that isn't just limited to screen space and ofc, there is pathtrace mode that uses far less shortcuts than lumen and still manages to be slightly faster than cycles. Dont forget, with post processing, you hide a lot of issues which is why UE5 lumen is used in some big budget movies and tvshows even if its quality is not 1 to 1 to offline renderers.

[@JohnRiley-r7j]

Cycles is powerfull but you need to own render server or pay to render your project.For 5 minutes of video you are into two days and two nights of rendering time on average GPU,this is just to long. Lumen is amazing,you can render same stuff in 20 minutes or so,and then put the project in after effects or premiere to fine tune it.

I tried multiple times to port scenes from Blender to Unreal Engine, so I can render them without massive render times. Sadly, it takes way too long to make things work in Unreal, especially if you don't encounter some sort of bugs. - All materials exported from Blender to Unreal have to be rebuilt (plugging textures and all)... Not practical with a lot of objects! - SSS don't look that good, and I think there are errors still with Lumen - Hair grooms are often buggy (especially with lumen) - Most rigs are not straight adapted to work with Unreal, especially with ik / fk switch workflow. You have to prepare for Unreal rendering before starting a project! - Alembic exports are bugged, like to get the scale correct I needed to export multiple times to make it work - Drivers are not compatible with game engines, making a lot of things just not possible, unless you rebuild it all yourself with nodes or code. Not practical for artists. That being said, it's fine if you plan to render with Unreal before starting a project, but it's not a very good idea to "port" blender projects into unreal. Static scenes and simple rigs should be fine though.

[@davidkohlmann]

Some good points I didn't cover. Fair enough. Seems like some solid points that makes it way more painful in some cases. Ty for sharing your experiences 🙏

[@yorden888]

agree . if you goal is to do simple rendering or simple animation , I would not bother export to unreal and redo all the settings , also if you computer isn't that powerfull , blender eevee is pretty much the best option, but if your goal is to make like game or interactive experience in direct time , maybe UE is okay.

[@locinolacolino1302]

It'd be cool to discuss a .usd workflow into Unreal.

[@kunemann]

true. i tried a tutorial once and it was hell

[@chlbrn]

Have been with UE since 2014 when UE4 just came out. Now I prefer Blender over UE if I make stills. I have multiple reasons to support. 1. UE is fast when rendering, but UE only works on GPU, meaning your VRAM is a bottleneck when rendering large size images at high quality. However, in Blender, you can choose CPU to render if you don't have enough VRAM and you can buy RAM sticks to add them up while you cannot do that with VRAM. 2. You need to optimize your scene in UE, tweak a lot. And that also takes a long time. Moreover, if you make changes for your UVs, models, textures, rebaking and reimporting will be a pain. 3. You can choose different 3rd party render engine for Blender. You can find renderer integration into UE but they work choppy and not for fast real time render. TBH, UE is still more suitable for making VR, games, previs, but not final renders.

[@flonkplonk1649]

In Blender you also can use shared memory GPU rendering (CUDA instead of Optix) and always use command prompt rendering instead of opening the program! Since then i never experienced VRam Memory issues anymore..

[@BenleGentil]

I have a hard-time seeing the benefits of a mixed-software solution over using just Blender in a professional workflow. Most of your tutorial focuses on the post processing but the time-consumming part is (properly) porting your assets from Blender to UE (including materials) - which you'd have to do for every project (whereas the rest can be a template done once) or everytime your client asks for revisions Also IMO the greatest strength of Blender is it's library collection (especially for interiors) that you can drop in minutes to populate your project - if those need to be remade every time it's a huge waste of time. Or you end up with an uncomplete project on Blender by using specific assets in UE which also hinders the creative process. 'Maybe' for video the benefits outweight the time spent but it seems to me that you have a hardware problem. Granted I mostly do still renders but with a 4090 my 4k renders take less than 3min and with a proper setup on deadline I don't even have to stop working while it renders. Make to math to your hourly rates but buying an extra 4090 (or even a workstation with 1-2 inside) will pay for itself whatever your hourly rate is. Disclaimer - I really which that UE was a proper upgrade over vanilla blender, I think interactivity is the killer opportunity here. Also don't be so quick to disregard EVEE, with the next version it's making a big leap forward - while nothing like UE it will be a massive gain of time for a lesser loss of quality. Also maybe omniverse is a promising solution to smooth the workflow (haven't tried it yet) Cheers,

[@davidkohlmann]

I got your points, but you're speaking from a professional's perspective. Most of people still doing this work in there freetime and also a lot of people don't even have the money to buy a 4090 or two of them, lol. So your perspective is very special and you may are right in a privileged position, With many, well-paying customers and enough money on the edge to spend thousands of euros on a high-end workstation. I guess that's not the standard. So you shouldn't just see your point of view. But for all professionals, true, go for 2x 4090 and push your fully realistic UHD cycle renders in some seconds each frame. I can't do it yet xD

[@sebastianodibusti]

I support your point bro, it is beautiful to dream of having an RTX4090, not to mention two haha

[@BenleGentil]

@@sebastianodibusti in all fairness the 4090 is only necessary if you need the VRAM, a 4080 gets you most of the way

[@theftking]

A 4090 doesn't really make a huge difference here. Unreal renders so much faster than Cycles. My 4090 seldom gets a even a simple interior cycles render (with no volumetrics) done in less than 7 seconds, and that's with OIDN. If Unreal can render that frame always as well in 1 second... that's a huge difference. That said, rebuilding the entire blend file in Unreal is way too much work, especially if I need to animate the camera in there.

[@BenleGentil]

@@theftking Not only rebuilding the file but having to do that back and forth for every client revision rounds / project and never having a final view of the project before getting to unreal. That time difference only matters a) if you're seating in front of your computer while it renders b) if it's not done rendering when you get to work the next day

In blender you can toggle backface culling to do what unreal will do and not show a face from the inside.

You get the 'lighting needs to be rebuilt' message if you're using static lighting for baked lighting scenes. If you set your lights to moveable (under the transform details) then they'll be dynamic and you wont get bothered with that message. Unless you specifically want it baked.. i.e. shadows wont move when the light or object moves etc.. which may improve performance, but basically it's the old way of doing things which is still lingering in the engine.

[@carlosmarx2380]

this is awesome when you need real time rendering. way better and faster than Eevee (i generally think Eevee is quite weak). but definetly not better than Cycles. I think for the most part, Cycles is worth it, if you have the time. also, like you mentioned in another video, you can easily get render time in cycles down to around 20-40 seconds with very little quality loss. for me, exporting and baking the stuff would take more actual work time, then just rendering it in cycles.

[@davidkohlmann]

Absolutely true. Cycles quality is stronger because it was made to create realism without "fake" calculating light, reflections, shadows and so on. And yes you can decrease the render time to a small number. But not in every case. Like a lot other people also recognized, it works better with darker scenes. I tried it with this corridor entrance, but it looked not good, at least not the way I wanted. If you render just single images or a very short animation and still want pure realism / quality, blender is your choice. But unreal makes other important things way easier. Lens flare is a single click in UE, in Blender you need some knowledge in the composite settings to create it. I also did a video about this couple month ago xD. I guess it depends a lot on what look you prefer and how much time you have.

[@TheBlackGamerPT]

Just an heads up, if you are using procedural materials and rendering a scene at the same time, it will take the triple if not the quadruple of the time since you are using formulas to produce textures. So if you bake the procedural materials and import the textures to unreal, it will obviously take way less time to render since its not using formulas or math anymore. Perhaps its equally as fast on blender if you dont use procedural materials and only use baked textures, but I might be wrong.

[@davidkohlmann]

The build time is reduced in this case right, but the render time itself not. The calculation of your scene, including texture etc starts first. If everything is calculated and loaded to your ram and vram, it starts rendering the image. So it should affect the time overall, but not the rendering process. And no matter what you try you are not able to render high quality in cycles >1s each frame. Even simple scenes. (maybe if you render the default cube base scene xD)

[@aurelienmartineau3D]

Actually it is quite easy to reach cycles quality with eevee when you know how to light and use the compositor to push it further. I have made several motion design projects with game engines and it was great to have such a high rendering velocity BUT IMO it is simpler to work directly into a DCC software : no conversion, no baking tricks, no first big project to setup that weight multiple Go on HDD just to make a simple render, no trip and trick to collaborate with other artists like for exemple a versioning tool or archiving the project in zip file cause it won’t work a NAS (too much files and dependencies), plus other artist are not always skilled to use a game engine…. And so on…. So when I discovered blender and eevee it was like a blast for me, everything is simplest to setup and share (you can pack all your dependencies into a single blender file for exemple). I get around 20s to 1m per frame wich is fast enough comparing to the complexity to use a game engine (even if I got here 1 to 2 second per frame). It depends on your needs…

[@davidkohlmann]

That's right, you can set up eevee to look similar to cycles (at least in most parts) And you get the render time still down to a minute or so while having good quality. But aren't you thinking, if you have multiple minute animation, it's worth to give UE a try? 20k frame with 1min each is still around 13 days, while UE can render this in couple hours. For me definitely yes, thats why I created this video. But I got your points, thx for your time and sharing your opinion and experiences 🙏

[@WifeWantsAWizard]

Excellent video. Interesting pipeline. (4:50) UE should add a "Flip all normals to Camera" option to prevent overlooking one or two while doing it by hand. Also, "2-sided" normals are bad for rendering times, despite your insistence that's negligible. Regardless, you can just shift-click all wrong geometry, then go to "flip normals" under "mesh edits". (9:00) I get where you're coming from with a shorter "render" time, but a lot of these post-processing bits are just doing the rendering in stages vs. simultaneously during "render time".

[@davidkohlmann]

Thx for sharing your experiences ❤️

UE sometimes for me often crashing. In project setting not need enable lumen. In post procesing you can enable lumen and lumen quality choose, i believe. And if you rendering in lumen, then path tracing not need enable i gues.

This video was excellent! You are the only person who addressed both the streaming pool error and lighting rebuild! There are 2 questions i have. One is can you do a video on saving in unreal because its not as easy as blender and reopening a project asks to rebuild level but it doesnt rebuild. 2nd question is there a way to export blender enviroment as a 3dgs and import this into unreal?

[@davidkohlmann]

Thanks :) I keep your first question in mind, but for the second one i would have to do a lot of research and it's not really my area of ​​interest. Try to find an expert for this, because iam not realy into file formats. Much love

That's what I watched too. 😂 To be fair, it seems like the benefit of this plug-in is especially for animations. You still need to set up our materials, procedural textures still need to be baked and stuff like that. (maybe lamps and camera are transfered better, but I didn't see it) But I though it's more like a one click solution, it's not. Al least it seams like not. Maybe iam wrong and some has experienced this plugin and can share it with us 😊

Great description..only it looks like your Unreal scene is also the lightest in terms of geometry and lighting, so it would be fair to have a more apples to apples comparison, using the same scene/relative quality, especially when you show something like that in your thumbnail.

[@davidkohlmann]

i dont understand what you are talking about? Its the same scene in blender and unreal. The thumbnail uses the render from cycles, eevee and unreal of this scene.

[@evans_archviz]

This highly depends on your desired outcome, if you want to get a few still renders you can set the render format to png and render animation by keyframing your camera to a different location each frame, also short animations are okay, simply render while you're sleeping... UE5 Is completely mindblowing but sometimes the time a project needs to be imported is just not worth it! Also cycles lighting is more accurate than lumen

This works very well, and i wish we had some nice Bridge to Unreal, like the bridge to 3dcoat. There was a small add on for blender, for easier file setup for unreal, but this was not very helpful, at least for the things i do. If this node and procedural approaches raise more in Blender, maybe we got some day a bridge to the Engine, like sideFX Houdini. I guess this would be the master tool.

[@davidkohlmann]

Agreed✌️

[@KenHeslip]

Exporting to USD instead of FBX might be worth a look.

of course rasterization with some ray tracing thrown into it is faster than full path tracing with a couple thousand samples per pixel, who would have ever expected that

Hi can you make an updated or part 2 version of this as people in the comments have given great tips added to the already great video? thanks

Sure, but not in the next days. I will combine this with eevee next, if it's fully developed and in blenders LTS version I will compare them together and also update the UE workflow.

[@iulian_98]

Have you tried giving the Cycles render engine a real shot? I mean to make optimizations? For example, what number of samples did you use? Did you use PBR textures (what resolution) or procedural textures? Did you use CPU rendering? Or CPU + GPU? What version of blender did you use? I did an experiment earlier with the exact same project and was pleasantly surprised to see that the newer version of Blender always renders the exact same scene faster with the same settings but 1-2 seconds faster. Any version of blender renders faster than the previous version.

[@davidkohlmann]

Iam a Blender user, not UE5. So yes, I give cycles every time a try xD But cycles is not made for fast renders, no matter what you say, it's not fast. But it's extremely accurate. You can reduce the render time by a lot. But even then it's still not even close to UE5. UE5 is fast but need some settings to archive realistic results. And depending to your scene you see more or less a difference campare to cycles. UE is like the big brother of eevee, in my opinion. You can get close to cycles, but not better, except you prefer the look of UE. Both softwares have it's strength and I like to combine them😊✌️

[@30Salt]

Have you looked into how speckle can be used to design and iteratively render with UE5?

[@davidkohlmann]

Idk what u mean

[@30Salt]

@@davidkohlmann The speckle connector for unreal. I've not tested their unreal connector myself but using speckle with grasshopper and blender has been a blast. Would love to hear what you think about them.

@@30Salt uff no idea, never tried this out. If I'll do I'll let you know. ✌️

[@30Salt]

@@davidkohlmann I would really appreciate that. In a lot of design work I have to go back and forth between visualization and design and can't afford to do the manual tweaks you've demonstrated in this video. Which is why speckle has worked so well for me because it preserves material settings and I can work on both design and visuals in parallel.

[@sirflimflam]

This is a really cool worklflow, but it's a shame at the moment you need to do so much work transitioning between the two. When someone creates a proper bridge that'll be amazing.

[@grbimagem]

have you added the time to prepare the Blender scene to export and adjust it at Unreal to the total Unreal render time?

Is it that "1 hour work instead of 2 hours render" situation?

[@gart2888]

What about evee next? would there be a slight improvement?

[@davidkohlmann]

It's still in alpha version, that's why I didn't talk about it. As long as there is no stable version yet, it wouldn't be a solid comparison. I will cover eevee next if it's in the LTS blender version.

[@Beef3D]

As an ex Cinema 4D user, Still, rendering in blender on good hardware is nowhere near as slow as trying to render something on C4D.

[@davidkohlmann]

i dont know how C4D is, but i know blender can be painfull in rendertime XD

[@Beef3D]

@@davidkohlmann if the free pricetag on blender isn't already an obvious giveaway, Cycles of course depending on your scene can be taxing, but it is far more versatile if you want to render in different gradations of quality. like, you could perfectly get away with rendering a stylized animation in Eevee and it would be fast that way. from my experience in C4D, rendering that same quality in c4D would take at least twice as long. it's hard to explain, but Blender just seems way better optimized when it comes to the built in render engine.

8:06 have you found a way for stopping the glass’ IOR going strange and glancing angles like at this timestamp (look at the window at this timestamp), in real life the window joinery doesn’t do that when looking through the window at an angle like this.

[@davidkohlmann]

I know what you mean without checking the timestamp xD Honestly, not yet...because I didn't had time to do more research and testing until now. But it's definitely something I am sure there is a solution for it. Unfortunately glass in unreal isn't as straightforward as in blender. Maybe you need 2 different materials, one for flat shapes, another one for curved shapes, but I will take my time to test this. And when I found the solution, I will share it with you 😊✌️

[@Josh-hl8jl]

this is the first time i heard someone say cycles has low quality. it literally is a path tracing renderer that can produce way more realistic graphics than a standard renderer like ue5 and evee

[@davidkohlmann]

I never said cycles quality is low lol xD I just made a compare between 3 animations, Where I showed that I had to lower the quality of cycles so far to even finish the animation and it still took 5 days. Of course, you can read my statements out of context, but it's just not very smart. And in the beginning I said that cycles is more accurate... But yea, it takes ages to get finished.

[@FlooferLand]

There is a big problem using Unreal Engine for rendering. If you have any GPU that's worse than a 3090 and you're working on a pretty big scene, it's just going to run out of VRAM and crash. I worked on a pretty tiny scene using nanite and lumen and I could not render at 1080p due to the engine constantly crashing

[@davidkohlmann]

With my 2060 I also got some struggle sometimes. But in most cases it was fine. Just if I exaggerating with 4k+ textures and nanite stuff 😂😂

Isn't nanite supposed to make the load on vram lighter since it loads directly from ssd?

I am experienced with Unreal, new to Blender and the most annoying part is the materials and setting up / fixing your scene into UE5. If they bridged those problems, damn I'd super happy !!

There is a way to safe materials into an fbx file. If you import this to UE, blender or other 3d software, the material will be set up automatically

[@mehface]

As far as I am aware, Lumen isn't great with flat surfaces too, plus it doesn't like surfaces to be attached, like 4 walls and a ceiling. These need to be 5 separate walls with thickness. They also need to be the correct scale. If your scene comes in at 0.01 scale, do not scale it up in unreal, do that in blender and re-export, lumen is much more accurate that way. Someone correct me if I'm wrong.

[@s1p0]

Gaming Lumen is a nice compromise between quality and speed (although I can see noise and optimization artifacts in Unreal).
