I didn't use the program for like a week or so when opened it, it was like this
and didn't know what had happened, when started to look around my files they were all like that
checked all the textures (they were fine), check rendered mode (it was exactly as I left it). I have no idea what could be the problem and from certain angles, I'm having way too dark shading. please help
EDIT: it has no light in the scene and the metacaps are off, I checked
