Texture-painted images turn black when used? I was experimenting with texture painting and noticed something really, really annoying. 

I spent 15-30 minutes painting, saved, then used the map as a texture. Note that I saved immediately after painting and before setting the object texture. 

As soon as I did, it turned black. I couldn't make it go back, so I quit, making sure to not to save the messed up image. When I opened the save, the map was still messed up. 

Does it automatically save changes to the UV even when the blend it's self isn't saved?
i had this problem ... you just open a new tab and open the uv/image editor , in your 3d view go into edit mode for the object you want ( which is black ) , and then in the uv/image editor , click the texture panel and select the texture you want .
