So, I have been looking through a lot of videos about Texture Painting. But mostly, they are in Cycles Render, I use Blender Render. However i did find tutorials about Texture Painting in Blender Render. But whenever they use it they say "Blender automatically adds a texture itself" and goes into Texture Paint mode with being able to draw. But when I literally do everything they said. Unwrap it, Add a new texture and go into Texture Paint mode. I did it all. But when i do go into Texture Paint, it says "Missing Data" and "Missing Texture Slot". And the cube i was supposed to Paint is also white. I might be missing something really obvious. But i cant seem to understand what it is. Some help would be appreciated. Like really, I feel desperate once again.
