This question already has an answer here:
I'm working on a model at the moment and I've spent hours texturing the torso of my character. The node setup is okay (I think), the paint worked perfectly, it was all fine and dandy until I stopped to texture a 2nd object. As soon as I had done this, the texture on the first object disappeared entirely, to be replaced with solid black. I suspect it might be something simple, but I honestly can't for the life of me figure it out & would really appreciate some help.
P.S I did UV unwrap, did create an image texture, and the image texture is still saved in the blend file. Did I need to save the UVs somehow perhaps?
