So I've been experimenting with foliage in Karma, using the new stencil maps. But Ive noticed my assets (in this case moss) becomes completely black at a distance. I have thinwalled SSS on them since that seems to be the only way to get translucency on XPU. Maybe there is a better way to do foliage material that doesnt have these issues?

I suspect its a mipmapping issue, and maybe related to the diffuse texture (rather than the stencil)

What happens if you run with this envvar?
KARMA_XPU_DISABLE_MIPMAPS=1

It seems to have helped but not fixed it entierly
