Hey.

When i try to generate clouds in the volumetric clouds tutorial, I always get this Error: Can't create texture 256x32x256, type L8A8, mode 1. After that, the program exits.

I couldn't find another post about this in the forum.

it's possible you're using DX10, which doesn't support L8A8 textures.
I didn't found the time yet to add vol clouds support for DX10,
you can use DX9 temporarily.
