After some searching around it appears that about 8 years ago it was possible to blend textures as driven by vertex colouring provided it was setup properly in the material node editor.
Having a search around now i can’t find those options, is it possible in either blender internal or cycles to do this?
If not is it planned?
I’m interested in this as it seems using the vertex colours are still a popular method of blending textures in various game engines.
Thanks for listening!
