How to use texture paint in Blender Render I had to use the edge split modifier and it makes my model IMPOSSIBLE to unwrap, so I just had to project from view, now its basically necessary for me to finish with texture paint but I have to keep it in blender render because the model will be going in a game.  When I select texture paint in blender render the model is just purple.
Never mind I got it, I had to add a texture image then select the texture that I had on the UV map.
