Black foliage? Light baking issues.

jordank95

Im getting really weird baking issues with my grass foliage. I have my grass set to use a Detail Mesh on my landscape. I set all my lights to be static and baked (Im not using a directional light, only point lights since its a night scene). Everything bakes fine, except now the grass mesh is completely black after baking. The mesh has lightmaps. If I set the lights to be Mixed, the grass is fine. It's only when the lights are set to static/baked, the grass turns black. 

What do I need to do here?

Hi! Don't know if applicable here, the terrain-documentation mentions that lightmapping is not supported with GPU instanced details. 

To check whether the gras mesh bakes itself bakes nicely, I would light-bake it in a small scene (has non-overlapping lightmap UVs, sufficient resolution).

With lots of foliage lightmapped, I can imagine the lightmaps taking up significant amount of memory. Might be worth checking how sample projects do this and possibly adapt their solution.

Good luck!

@Fabi_G ah you're right! Setting it to Grass mode instead seems to fix the bake issue, though now I'm dealing with another issue with the built in wind system.
