I would like to scroll another texture on this black texture which is a model texture. I can't set the model invisible ( or i don't know how). I want my knife looking like on this video : http://www.youtube.com/watch?v=Ygl7V0AO4oM
But with transparency instead of "black"
. My both scroll shaders work, but not this one.
I can send you all the textures im using to get this render if necessary.
