The image I created in blender and painted as my texture map has been blanked out to a total white image. TWICE. To make it far worse, this has affected all the save files of this project. The first time I finished it, left my computer for an hour or so and came back to it being erased. The second time I was on to baking the normals, messing around with multi-res mods and it abruptly was lost again. But again, the first time it just happened for no reason out of nowhere. I even did "save copy" the second time and the texture in it, and all 10ish saves is gone.
I have to assume the texture images are saved independent of the .blend files and somehow it got corrupted. The thumbnail for the image still shows my work, but the image itself is just blank white. Saved to external .png and confirmed. I'll try not to rage about the 4+ hours of work that vanished. Any ideas what the problem could be or how I could recover the texture ?
