Materials, .dds files and co...

[Ludvearty]

Hi !

Simple question, because i'm not able to find something about it..

How do I make a custom materials (in order to create a decal of grass) ? I watched how the current decals are made : diffuse map, specular, and normal.

But the nVidia plugin in photoshop makes me white .dds files oO I don't know what presets I have to use !!

Thanks for any help, I can't continue without that x) !
