There’s still a performance loss by doing this, but not nearly as severe as without Nanite. I also experimented a lot with what foliage needed shadowing and what did not, and how culling distance on foliage affects fps. The foliage tool has a filter setting that tells it what kind of objects it can place foliage on (landscapes, static meshes, bsp’s etc) this tool uses an objects collision to determine where the foliage is placed, so keep that in mind as well. Remove post processes and etc. This is what you put in foliage mode. RayTracing. Use all 3 applications. Orbit Studio: r. g. A common workaround is to use a 2d distance field texture for the alpha and set its threshold according to the distance the camera is from it so that the alpha expands out as the mesh gets further away. In my current, nearly solved project, they've been scaled up to around 3-5 and are being scattered by a Houdini scatter tool I created.

Only cull related settings I have in my foliage menu is Cull Distance, but instead of start/end, it's min/max, minimum can't be set to anything besides 0 and max can't be set to anything besides 1, so it's from 0 to 1. Set your lowest detail LOD as billboard/2D plane, with a render of the plant/tree applied to it. Additionally to the Volume I set the Cull Distance in the highlighted wild grass foliage. I found for example, nanite decreased performance when floodfilling a giant map with a bunch of instanced cubes. Foliage clusters actors together and culls them at a specified distance so it's a great way to get instant performance benefits. Does anyone know specifically what causes this and how to solve it? I am so ready to start using Lumen & UE5 but this is the final issue I can't seem to resolve. Besides changing the culling distance and what have you, there are other tricks like making it so the material the grass is actually on is colored/textured similar to the grass's hue and brightness. A custom shader is used which hashes the translation portion of the instance transform (which gives you a unique hash per grid cell), then uses that hash to generate a randomized rotation and small offset transform to push the grass bunch off the rigid grid Another place you might want to check other than lod culling settings is the actual material itself. An easy way to do this in UE4, should be in UE5 but I don't use UE5, in the console, there are showflags so you can go through and turn off all the post process, mesh, and effects, and anything else in the console during runtime while it's happening.

Have you tried adjusting the LODs to use more aggressive triangle reduction? Also you may want to check your culling distances and make sure your start and end distances are set appropriately so you have a nice balance between rendering the trees you can actually see and hiding the ones far away in the distance.

Edit: If anyone had the same issue with culling due to long distance between areas and are fine with adding a little c++ I was able to get the landscape and foliage (i e. That’s from the documentation. Merging them doesn't reduce draw calls and has the downside of increasing the poly count and ruining occlusion. exe executable file.
