I'm new to Blender, but I have used Lightwave. I've seen a weightmap used with instancing, like where some plants should grow. But I've never seed a weightmap used to control a texture using either procedural or image maps. Why is that? Can it be done? thanks
As far as I know in Blender weight map just defines a vertex group.
I haven't seen vertex groups as a way to control textures but you can do that with with alpha maps (black and white all the gradients in between) with either ones created procedurally or painted/created by yourself.
