I want to share a tutorial my teacher from 3D modeling and texturing made for us. It is about Vertex Paint option. I'm sorry it has no sound, but if you are little litearte on 3D max, you will get it all.
You can find video link in doc file attached(I had to upload it through wetransfer, because it's size is 19MB, so I cant upload it on here )
(it is a .swf file, so you will just need Adobe Flash Player)
As you can see in pics attached, you will be able to paint over your geometry and texturize it after. Very useful when you want to texture a terrain surface.
I hope you can find it useful!
