10 Minute PCG Forest in Unreal Engine 5
In this tutorial, I will show you how to create a procedural forest in Unreal Engine 5 in just 10 minutes using Quixel Bridge assets and a free PCG plugin. I'll guide you through setting up landscape materials, adding procedural grass, and spawning trees and rocks with precise placement control. You'll also learn how to modify plugins for better integration with auto materials. This tutorial is perfect for game developers and environment artists looking to create realistic forest scenes quickly and efficiently. Watch now to master procedural content generation in Unreal Engine 5!

Nanite Forest Optimisation in Unreal Engine 5
มุมมอง 13K4 หลายเดือนก่อน
In this video, you will learn how to optimise a forest scene in Unreal Engine 5.4 using Lumen, Nanite, Virtual Shadow Maps and Virtual textures. Optimised DefaultEngine.ini: drive.google.com/file/d/1o18QGV0UAJw68vbhtLHJAQmlaKyhKh60/view?usp=sharing 1) One more tip I forgot to add is disabling cast shadows on your landscape, but it doesn't look good in some cases (I didn't do it). 2) If you are ...

    Can't thank you enough for putting this together. I've spent hours and hours trying to figure out why my performance on even the simplest of scenes is so bad. It's crazy that Epic basically gives you the worst possible performance settings as the default and then buries all of the important features under mountains of config.

    Nanite landscape performs worse for most landscape. Don’t use it unless you want tesselation.

  • @marci1270
    @marci1270 หลายเดือนก่อน

    Just disable Nanite and use LODs, then you have the best performance.

  • @Switchpoppy
    @Switchpoppy หลายเดือนก่อน

    I think this video covers everything really well. I did some tests with Nanite Foliage with modelled leaves, and performance is gained when you have 300-400 trees on screen. These modelled leaves are using unmasked materials, each tree was about 200K triangles. This optimization is quite a small gain though, a non masked nanite forest would perhaps net you something in the +5fps range for that number of trees.

    • @Filgeck
      @Filgeck หลายเดือนก่อน

      Thank you for sharing! I played around recently with modelling grass with no opacity mask (the exact same shape) and didn’t see much improvement (although the overdraw was significantly better). One thing I noticed is that it looked different - it’s as if the grass at a distance wasn’t as dense. I would have never noticed it if I didn’t see how the old grass looked. It’s very minor and I guess shows what Nanite does to small objects behind the scenes

  • @schmutzxD
    @schmutzxD 2 หลายเดือนก่อน

    Hey buddy, I think I've noticed a problem here. It should be the same for you, I think I could see it at some parts of your video. The problem is that the shadows do funky stuff when you get up close to them, this is especially notable when you walk through the scene with a character. Only the very closest shadows are displayed properly, those that are like 5 meters away from you look much different than those that are right below you. When walking through the shadows you can kinda see the zones around you and the shadow updating in a very unclean way, also you can very clearly see the tiles in which the shadow map is generated (I think that is what you see? I'm not sure), resulting in some sort of different, sharp "loading zones" around the player. You can see those "loading zones" when you turn on the view "virtual shadowmaps -> cached page" in the editor (instead of lit/unlit or whatever) very clearly. The problem doesn't occur when you disable the World Position Offset of the master material of those trees or whatever is causing the issue. So the movement of the leaves and stuff seems to play a role in this? I've followed tons of ChatGPTs suggestions and tried many other things to fix this, but nothing seems to work. Do you have a fix for this? Help would be greatly appreciated! Edit: I've uploaded a video of this problem here: imgur.com/a/PlJuPZv Edit2: The issue also doesn't appear when you select "Auto" or "Always" for the "Shadow Cache invalidation Behavior". "Always" seems to be slightly more performance friendly than "Auto", but I guess the idea here was to avoid both of those options.

    • @Filgeck
      @Filgeck 2 หลายเดือนก่อน

      Hey! Thats a weird issue. I think mine is not as obvious as yours and when the trees are moving - pages update correctly. Not sure what this is caused by but try looking into increasing VSM pages pool size and texture pool size. If that doesn't help try disabling nanite, lumen and virtual shadow maps to see which one breaks it. Also try different trees from quixel in a new project.

    Great job! Scalability High targets 60FPS, Epic 30FPS on consoles. So using High as a basis is the best choice for hitting 60FPS, regardless of platform. Lumen Global Tracing uses the Global Mesh Distance Field, while the Detail Tracing also traces against per-mesh Distance Fields. For more complex mesh shapes, it can make a big difference. The Nanite landscape splitting you were seeing was a bug in 5.4. It is fixed in UE5-main, no idea if it made it into 5.4.4 as well.

    Great stuff. You can also use the “World Ray Hit query” node to sample and filter by physical material. This is what I did with my auto material I assigned the specific masks to a physical material so that each layer spawned its own set of meshes. Would love to see how to remake the Nordic Conifer Biome you had in your last video with PCG

    Great video and really nice looking forest! Just a tip regarding shadows on grass and other small foliage/assets for those who are not aware of it. Try using contact shadows instead of dynamic shadows. It is enabled per default on meshes, but the contact shadow length on directional lights are set to 0.0 per default. (I usually set it to 0.1 or 0.2)
