Procedural Content Generation UE 5.2 - In-Depth Overview & Building Forest Environment PART 2

Рет қаралды 14,051

Күн бұрын

Part 2 of my tutorial series on the Procedural Content Generation Framework in Unreal Engine 5.2. We will learn how to sample landscape layers and use this information in the PCG framework to dynamically spawn assets on these points utilizing the point filter node. We will explore a new debugging technique and lots of different PCG graph setups. We will then go into detail on how to setup a forest environment entirely with PCGs, starting from a grassland biome, a denser forest and finally some procedural slopes with foliage growing in-between the rocks.

For anyone following this in 5.3, the "Attribute Operation" node is now "Copy Attribute".

This is what is was looking for! Epic Games should add this to their tutorial page for Unreal Engine 5.2 PCG section. Amazing work!

Hi, I watched the ''Procedural Content Generation UE 5.2 - In-Depth Overview & Building Forest Environment PART 1'' video and really enjoyed it. The video was very detailed and informative about procedural content generation. After watching the video, I learned more about procedural content generation and how to use it in Unreal Engine 5. I would love to see more content like this in the future. These videos are very helpful. Thank you for making the video.

There's a lot of techniques in this one too, just check the chapter overview in the description to see what interests you. After this series, I might go back to shorter videos in the style of the first one, so stay tuned!

Thank you for making this! Amazing job on understanding the PCG framework. I don't fully understand how this all works yet, but it would appear you are spawning the initial surface sampler for every group? How does this go for performance on large terrains? I would love to see a video on optimisation, whereby minimising the number of computational steps. I.e start loose globally and only spawn on each landscape layer and, then densify from there only as required.

@exit-simulation Жыл бұрын

You are right, I am actually planning a video on PCG optimization as this environment is already getting quite heavy. Thanks for the feedback

Great tutorial! I'm not through yet, but what about the performance? Is there any chance that it can be used for a game? I have a 3080 and with grass and trees my framerate is already only 30 fps (in the editor). In another video, imposters were used instead of trees placed further away. Unfortunately I don't have enough experience in UE5 to understand how this works...

@seansopata5121 2 ай бұрын

we're using nanite. imposters aren't really relevant. That said, I don't think nanite is enabled by default on the megascans grass. Doing that should give you at least a small bump in frames

@vytasrauckis6703 11 ай бұрын

When I opened up the geometry spreadsheet I got all the information for the Surface sampler EXCEPT the three surfaces (base, grasslands, and cliffs). Is there something I missed to view those?

Make sure you created the layers in your material and properly assigned the material to the landscape

hi! great videos! it is so nice to have it all condensed like that :) quick question: how do you fix the issue at 18:30 with one of the assets being bigger than the rest? did you just got rid of it or is there a way to reduce/increase the size of just one of the assets in the array? thanks!

@exit-simulation 5 ай бұрын

Haven't found a solution for this yet but I am looking into it. At the moment I am trying to adjust all assets of one category roughly having the same import scale but it's far from optimal

@k3lk0m 5 ай бұрын

@@exit-simulation cool! thanks! yeah doing the same thing here. just grouping similar scales in the same mesh spawner and unifiying tranform and such with custom attributes... at least this way I can control them all transform and rotation wise but keeping scale control separately. awesome video btw, going back to it a lot!

Yes with spawn actor. I will use it for spawning decals in part 3 but it could potentially also be used for spawning animated actors.

@@exit-simulation i see, is it possible to 'kill' this spawned animator actors in the game ? to gain EXP. - player walk around the map, find different types of animals, shoot some projectile to the animals, animal Minus HP , and eventually dead and disappear, player gain EXP or gold.

@mathysvandermerwe6094 Жыл бұрын

@@chadgtr34 Cannot see why not. PCG would handle spawning. The actor should internally take care of the rest like roaming, eating, etc. (including of course getting killed and despawning)

@chadgtr34 Жыл бұрын

@@mathysvandermerwe6094 got it, thanks. one more question, when you say 'spawning' is it always refer to the game already started ? because PCG means we haven't click the Play in Editor button, and trees, grasses are popping up so that you can preview them and then adjust them.

@exit-simulation Жыл бұрын

With the PCG framework you can both spawn in editor and during gameplay, so both options are viable depending on how you want to set up your game mechanics. You can also decide per graph individually, e.g. spawn trees and environment assets in the editor and other dynamic blueprint actors during gameplay
