Procedural Content Generation UE 5.2 - In-Depth Overview & Building Forest Environment PART 1

Рет қаралды 39,003

Күн бұрын

In this tutorial I will show you useful techniques of the Unreal Engine 5.2 Procedural Content Generation framework for the creation of dynamic environments. We will learn how to use all of the basic nodes and create various PCG graphs exploring concepts like density filtering, difference & exclusion, density based on slope, spline sampling, exclusion of water bodies, point grids, mesh sampling and subgraphs. In the second part of this tutorial (upcoming) we will then use this knowledge to build a vast forest environment using just Megascans assets and the PCG framework.

Fantastic tutorial, easy and very well explained. Keep up the good work :)

btw you have to enable "PCG geometry script interop plugin" to be able to use the "Mesh Sampler" node

18:57 not sure what changed between 5.2 to 5.3 & 5.4, but using static mesh actors for difference nodes doesn’t work properly (tested in 5.3 & 5.4) This is evident if placing a translucent material on the exclusion mesh and debugging the points themselves. It only removes points based on the bounds of the mesh, not the interior. Current work around I’ve been using is Blocking Volumes instead with the same Tag method mentioned here. Maybe I’m still doing something wrong? Incredible video you put together! Very informative and helpful for those entering into PCG.

I finally figured out how to exclude the water body custom thanks to you my dude. it took me ages because i got so frustrated. to all lout there trying to exclude the water body from the PCG in cases where you have the entire map as a PCG and you introduce the UE water body. All you need to do is use Get All Actors node-->Set Actors to All World Actors-->Actor Selection will be By Class instead of all world actors. Then plug that into your Difference node!

Great tutorial. For Unreal 5.4, the "Input Node Settings" are marked as deprecated. I had to use a "Get Landscape Data" node as additional input to the Surface Sampler node to see anything - as I am beginner in PCG, there might be a better way!?

It should work the same, make sure your volume is intersecting with the landscape.

Great tutorial, amazing work done I subscribed, this chanel must grow. I have a question ... Everytime game starts pcg content will spawn in the same place? And what happens if a player interact with a pcg mesh (cutting a tree) the pcg will change all objects position? Or this can be saved.

@exit-simulation 11 ай бұрын

Yes it will spawn in the same place as long as you use the same seed for all your nodes. There's also the possibility to disconnect the pcg graph from the volume and "bake" your static meshes permanently into the scene if you are happy with the results.

Is it possible to have areas change what's in them. for example one space has trees, but the next time the game is launched there are houses in that space. I Haven't been able to watch the video so sorry if you talked about this.

@exit-simulation Жыл бұрын

Not sure I completely understand what you mean but you could swap out PCG Volumes dynamically. Generating a PCG graph works also in-game, so you can have a graph that spawns trees and another one that spawns houses and decide dynamically which one you are activating in the scene depending on certain conditions.
