Blender Render Texture Painting

Question

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.

(If you need more info I can spend hours typing it to you in the chat. I have no life, so i'm almost always online.) (I use Blender v2.79)

I think you're missing one main point: a UV map is needed to make a correspondence between the mesh faces and a texture to paint to. And this UV is to be set up in the texture panel.

So the recipe is the following:

• Have a mesh object
• Go in edit mode Tab
• Select vertices and unwrap (there is several ways to unwrap, I consider here the simple one): use U the "smart UV project" and validate

• Create an image
• Go to the texture panel
• Choose the texture type as "image or movie"
• Choose the image created above
• Set the mapping to UV

Now you can paint:

Note that there are possibly several slots to paint to and you can add other textures or texture types from the "slot" tab available in paint mode:

In complement, here is how to create the image:

• Open a new view
• Set it to "UV/Image editor"
• Use the "image" menu then "new image"
• Validate the panel that opens, eventually renaming the image as you want
