Create PCG Forest Path with Unreal Engine 5.3 - Tutorial

[@ricardobino7410]

Holly cow!!! this was way more complex than I thought, and he goes over everthing in 20 minutes.

[@mmmeiw]

Thanks for the tutorial!, just 2 fixes that i want to share for those having these problems, before starting the tutorial, turn on the plugin Procedurial Content Generation Framework, or you wont find the PCG component, and if your spline doesnt spawn any mesh, open the PCG_CopyPointsWithHierarchy, and connect the unplugged nodes, mine came unplugged for some reason, after that it should work.

[@CGDealers]

I'm pinning your comment so people can avoid those mistakes :)

[@thebenga05]

Same problem here, unplugged node. But I still have a "missing blueprint" message on this (previously unplugged ) node, do you remember which "Blueprint Element Type" I need to select in the properties to make it work again ? It is set to none right now.

[@Soreja-i9l]

@@thebenga05 It's the "PostCopyPoints-OffsetIndices" ;)

[@biobaumag6359]

Startet learning PCG about a month ago and there where no good Tutorials on the Internet. That helps so much. thank you

[@CGDealers]

Great to hear!

[@IstyManame]

omg the timing, i just started learning pcg today

[@CGDealers]

Reading your minds :))) This will be very useful to you!

[@Silpheedx]

Thank you so much for this tutorial. But in the future when you are building the graph if you could slow down and explain what each part is doing visually I would personally greatly appreciate it.

[@CGDealers]

Thanks for the constructive feedback! I will take this into account and do it better next time! Consider it done!

[@micah64]

Thanks for making this tutorial! But one call out for future -- it's really appreciated if you make the video thumbnail reflective of the final result of the project, rather than a stock or unrelated photo!

[@CGDealers]

I fixed that. All my recient videos are like that! Thx!

[@ToysRUsKid_Critter]

I love this channel. Yes, I’m part of your Patreon crew

[@CGDealers]

Awesome! Thank you!

[@wielandsmith]

Great tutorial. The only thing I would have loved would be more information about the various nodes you are using - the whys and hows, etc.

[@CGDealers]

Noted! Will do!

[@DaRealGoosebumps]

Is it possible to create 2 or 3 level instances of that road asset and randomize them along the path? Would be super cool if that can be done. Amazing tutorial, thank you

[@CGDealers]

Yes you could do that.

[@DaRealGoosebumps]

@@CGDealers that's great, but something is not working for me. I repeated the tutorial 3 times and I still end up with an empty spline. Im using 5.3.2

[@shadowknightff]

Will you please try to create desert dune environment 🙏🙏

[@emersonharropcgi1983]

Hi, ive downloaded the custom nodes from the electric dreams set, but i only have 2 show my folder and both of them come up with an error saying "Blueprint could not be loaded because it derives from an invalid class. Check to make sure the parent class for this blueprint hasn't been removed! Do you want to continue (it can crash the editor)?", im not sure what this means or what to do. would massively appreciate any help! thanks:)

[@danielmiller2462]

Any Luck?

[@stevenseidler9314]

ive got this problem too

[@valgau9488]

turn on the plugin Procedurial Content Generation Framework

[@xjuliussx]

love your videos, is what i was looking for last 1 year or more. Still no solid informations on the subject how this can be procedural.

[@CGDealers]

I hope this helps.

[@violentpixelation5486]

On point! 💯🔥👍

[@CGDealers]

Thanks 💯

[@bendiba28]

Hi! thank you for this tuto, it makes it all clear!!! However I noticed that if I add blueprint (assembly of bunch of SM) into the level instance, it spawn it well but the transform point mess up the layout of the static meshes contained into the blueprint actor... is there a way to apply transform to the blueprint as a single entity rather than applying random transform to each SM separatly??? Thank you

[@grapho13]

amazing tutorial, thank you for share

[@CGDealers]

Glad you liked it!

[@jayhop960]

you are so awesome, like you helped me here so much, i was soo sick and burnt out on trying and trying and deleting projects and then you release these awesome tutorials thank you seriously, but one question, how do ytou import the heiarchys

[@CGDealers]

Import the hiarchy?

[@jayhop960]

i got it now nevermind thank you sir@@CGDealers

[@jayhop960]

but im still having issues with the blueprint actor@@CGDealers

[@tanyabricker7902]

I followed every instruction and even watching other videos to complement, but for some reason my level instance is not shown, the line appears but without any mesh. I installed all the plug-ins from Electric Dreams and I migrated the custom nodes, but even with that, I can't visualize the Blueprint correctly. Please Help!!

You are great!Thanks for tutorial

[@CGDealers]

Glad it was helpful!

[@danielmiller2462]

Amazing Video as always! Came across an issue that hopefully someone can assist with. I am only able to spawn one instance of my path, even when I manipulate the spline and add subdivisions. Any help would be amazing, thanks! Timestamp 18:26

[@TolisPiperas82]

Is there tutorial where you make this piece?

[@CGDealers]

Just download assets from Quixel and moving, rotating and scaling them. Nothing so special about it. Just take your time, download assets from Quixel Bridge, get a reference from real world and start mimic it. You just use Move/Rotate and Scale tools :)

[@henrygonzalez3841]

I have repeated your video more than 5 times, I have started from 0 each time, but for some reason my objects are not shown, the line appears but without any mesh, do you happen to know why this happens?

[@lucianogatto7949]

Check the PCG_CopyPointsWithHierachy node that he asked to download, it came broken and he forgot to mention on the video you need to fix it. Just look at the frame of when he has it open and copy it. You need to drag the PCG_PostCopyPoints-OffsetIndices

[@croustib4t207]

@@lucianogatto7949 Hi, just tried this solution replaced the node by Post Copy Points- Offset Indices and like henry said I have juste the line of the spline and nothing shows, also double checked everything. Another comment suggested to install "PCGBlueprint Element" but didn't find it in the Electric Dream Folder

[@tanyabricker7902]

@@croustib4t207 Hey, did you resolve the issue? I have the same problem and I can't figure what is wrong.

@@tanyabricker7902did you get this fixed? I was having this issue and I deleted the pcg settings from my level instance and the remade it and added it back in. It then spawned my instance but I can’t figure out why it will only spawn one.

[@petero1146]

sadly same here. No mesh spawned. I tried everything mentioned above. May it be Unreal 5.4?...Thx!

[@rahulnmahajan7224]

Can we remove pcg after creating this path and use that path actor in other maps?

[@CGDealers]

Like bake it?

Hey, pivot point of my blueprint class is far from the created level (pivot point of the level is placed in the middle of it) I think the problem lies with the spline starting point - is there any solution to fix this ?

[@fandomscreenshots]

Is there any way to optimise the trees? Because whenever I add a lot of them, my FPS drops drastically and it seems Nanite doesn't do a lot

[@CGDealers]

You need to optimize the shader and geometry, use LODs etc.

[@fandomscreenshots]

@@CGDealers Ahh okay, the thing is that in the description of the tree package it says it does have LODs so I expected a smooth performance just like in your video

Hello, i got to the point filter part and i get a warning saying "1/1:[PB_PCG_Spline_C_2] Warning: TargetData doesnt have target attribute/property 'trees'", its saying this for all of my point filters, if its refering to the tags, ive tagged all my assets so im not sure whats causing this, any help?

It should be from the tags. Hop into discord so we can help you out.

[@thisisriil]

Found this issue as well 😢, did u guys resolved it?

[@valgau9488]

You need to recreate your PCG Settings from your level

[@AdventureMine9]

why i do not have the append attribute set?

[@RkOiller]

same here -- i have 5.4.1 version installed

[@AdventureMine9]

@@RkOiller news?

[@CGDealers]

I guess they substitute it with another node in 5.4. Go through the change log from 5.3 to 5.4 in Unreal official release doc and you will find what substitute it.

[@AdventureMine9]

@@CGDealers I ill try thx

[@DakotaGeorge3D]

It's called "Add Attribute" now

[@Soreja-i9l]

I can't find the "Append Attribute Set" (09:40 min). Does somebody know the new name for that?

[@Soreja-i9l]

It's called "Add Attribute" now. Just in case someone has the same question ;)

[@SoniaNandhikanti]

Hey, not able to add append attribute set, there is no option?

[@CGDealers]

The Append Attributes Set has been replaced with a more flexible and integrated system of PCG Attribute Nodes in Unreal Engine 5. These new methods provide more control, better performance, and a streamlined workflow when handling attributes in the PCG system, especially for complex procedural content generation tasks. The overall goal is to make procedural content generation more intuitive and scalable. If you're working within Unreal Engine 5's PCG framework, you'd likely rely on nodes like PCG Attribute Set, PCG Attribute Merge, and others to achieve the same (or better) functionality that Append Attributes Set provided.

[@SoniaNandhikanti]

@@CGDealers okay, Thank you!

why on earth is this channel demonetized?

[@ashusharma_]

how to import custom_node filein my project that not working in my 5.3 version

[@emersonharropcgi1983]

Copy the plugins folder from the electric dreams project to the plugins folder into your UE5.3 programs folders as you need the "PCGBlueprint Element" which is a C++ class then turn on the plugins in your project and they should be working, took me a while to figure that out lol. Hope this helps :)

[@ashusharma_]

thank you its working👍👍👍👍@@emersonharropcgi1983

[@thenetimp]

would be nice to have a tutorial that didn't require a download of a 55GB asset from the Unreal Engine....

[@CGDealers]

No need to download the assets. Use any other lowpoly assets.

[@nayler2010]

This is so broken the nodes have all changed aswell update video needed !

[@CGDealers]

I'm working on the water system now. Will update this soon. You could try to make this in 5.3 then update the project to 5.4 might work.

[@Bluuuee]

Is anyone having trouble on 5.4? I made some changes to my level instance of the path but its not updating to the blueprint. Its still using the 1st version that I created. I just wanted to move some rocks around. Tried hitting force regen in the PCG graph deleted the old level instance in the graph and brought it in again but it still wont update. Nevermind I fixed it lol.

[@kenjixo]

How?

[@Bluuuee]

@@kenjixo around 7:05 he was saying that you need to save what you changed and then on the instanced level of the mesh path you were working on you right click on script asset actions > PCG Level to PCG Settings. That should update the BP mesh with the changes you made. I guess I wasn't doing something right at first but then it just worked for me.

[@CGDealers]

lol, just about to replay

[@kenjixo]

@@CGDealers @Bluuuee thank you guys! For the last transforms the Hierarchy node after the merge seems to overwrite them. I ended up skipping them. Don't know if you run into the same issue!
