So I created some objects, UV unwrapped and projected them, painted on their textures and everything seemed fine. They were rendering and everything. I closed blender, and then re-opened it. However now, the textures I painted only show on the objects as black now! Although I can see the textures I painted in the tiny thumbnails in the images within UV editor, when I click on them they show up completely black as well! Does anyone know how to fix this?
