vertex painting

Can it only be used in games, if not, then why when I try to render a painted object it doesn’t show up, just the applied material, the clown tutorial didn’t show me much… how would i render a vertex painted object, and also, its possible to paint over some parts of a texture, if so, how? I’m using blender 2.4

There are two buttons for that in the Material context (F5) >> Material pannel. VCol Paint will do what you want and replace the colors with your vertex colors.

Happy New Year !
