I spent about three hours painting textures on to a creature I sculpted and decided that I wanted to add some hair to it. I go into edit mode and pick the circle select tool to select the portion of the head that I want to add hair to. I press the F key because that's what I thought was the shortcut for adjusting the radius of the select tool and then suddenly Blender just crashes. Now every time I open up the saved file all of the textures images are just gray. There has got to be a way to retrieve the old textures right?
