When I put foliage on the level, I should setup lods for my grass,my trees, everything? Because I put raw grass (as I got it from “community content”) on the terrain and my fps starts dropping.
So EVERYTHING must have lods? Even the grass?
Hi Innos,
With something like foliage you would definitely want to make sure that you’re using LODs for them. Especially since foliage typically will have some opacity or masked materials this can create a lot of overdraw that can added up as well.
If you’re still seeing issues after setting up some LODs for your meshes you should definitely take a look at Profiling for your performance issues. This will point you in a more consistent area to start investigating and reducing those draw calls.
Here is some of the documentation pages related to performance and profiling that could help if you’re not familiar with the system.

Thanks !
I think you use my grass package? 
-hey are not so optimized -> either add LOD’s or reduce the masked part of the mesh
-use the “basic” material -> no complex wind and unused effects
-use a good density -> not too high
-use a good ground material so that you can use a lower density
