Hi, I’ve created a model some weeks ago and painted the textues on it using the texture paint tool. Now I tried to reopen the blend file and all painted textures are black. Only their small thumbnail in the image viewer dropdown gets shown, but they are all shown and rendered as pure black.
After you painted the texture did you save the texture from the Image menu. If you didn’t save the texture before saving your blend file there is no way to get that texture back.
