I couldn't find any threads on this subject, so I figured I'd post it here. If this has already been covered, I'll delete this post.

I wanted to figure out a way to use vertex painting to blend textures on a model. The easiest way to do it seemed to be the material nodes. Here are some images:

Base texture:


Dirt texture:


vertex painted material (Set to shadeles and VCol Paint turned on):


Final render:


It's a very simple use of the material nodes, basically I was looking for a way to quickly texture landscape meshes without having to use uv mapping. I used the vertex painted colors as a mask in the node editor to blend the two textures.

Here are the nodes:



Anyway, I'm a blender newbie, so any suggestions or different ways of accomplishing the same thing would be appreciated.
