Hello. Thank you for answer. Our project have static light enviroment and we really need good and cheap GI solution. Fully dynamic lighting just isn’t an option. We also need to support wide range of hardware.(including mobile)
I understand that landspace grass don’t use lightmaps because of its procedural/dynamic nature but same is true for all movable objects too. I assume that landscape grass chunk use single sample from volume light cache which causes discontinues on the edges and bad lighting when that chunk is only partially shadowed. Reusing landscape ligthmap for grass maybe could solve this.
I made minimal test project that show the shading problem.
