Ultimate FOLIAGE Guide in UE5

If you want to use nanite for foliage, the performance is greatly increased without using alpha textures. You will have better performance if your foliage is pure geometry (to some extent, you can't go super crazy with the vert count on individual clumps of grass). So take care to cut your nanite mesh out around your alpha texture. This is simply because overdraw from alpha testing is still one of the most costly things to render, so increasing your vert count with nanite levels is extremely heavy. There is also nanite overdraw to consider, which has to do with overlapping geometry. Take special care to optimize your geometry placement to reduce nanite overdraw, and make your materials for nanite foliage Opaque Subsurface to decrease their shading cost and have no regular alpha testing overdraw on any of it :) If you want to learn more about that check out Paul Mader's technical breakdown of nanite foliage for Fortnite.

Can i procedural generate trees with using some masks and have collision?

Salut, merci pour le tuto ! tu as un discord pour échanger entre passionnés sur unreal, les techniques etc ? je cherche à discuter avec des gens, apprendre d'eux, leur apprendre enfin je pense que tu as compris ! lol

great

This are golden guides! Thanks a lot 💪

This is great, well done. I love reviewing your optimization on foliage-landscape. May I suggest you revisit the latest IA scatter plugin and DASH plugin (previously graphN) and would suggest you do optimization based on the plugins for scattering? I love using IAscatter in conjunction with my procedural levels as it easy to use, including blueprint actors. Though dash is subscription its the fastest way and easiest way to scatter and dress the environment. PCG for me is still time consuming to setup unless more asset creators make more templates out of it or the examples from UE. So currently i mix dash and IA scatter.

Can you also cover HISM or packed level actors type optimization? Thank you so much

I always get the following message in the editor "video memory has been exhausted". The performance tanks very hard. I currentyl have an RTX3070. Any advice?

Another very well explained video

I really like the landscape material , did you make it or was it bought online .

bought M4 after you bragged about it,... cant seem to get the grass types to sapwn with either unreal sensai landscape or the M4 addon. even in the default island example map no grass
i dont know what im doing wrong

Thanks that was great!

Great Tutorial, big thanks ! but the challenge also, is to make a good foliage with path-Tracing, and believe me, it's quite annoying !!

I was having the same lod isuses with non - nanite grass... Thanks man..!

r.RayTracing.Nanite.Mode 1 Use this to remove black shadows on trees ;) instead of false back relative errors :)

So I totally shouldn't use nanite on grass/thin meshes? Isn't there other option?
