After playing around with a lot of SSS shaders and so on, I’ve managed to mess up a few surfaces in a scene, and not even applying the original materials helps. The only way to fix it I’ve figured out seems to be to add a completely new item and pose it to the same place and shape as the ‘ruined’ one. Or is there an easier way? Like resetting a surface completely to ‘zero’/‘default’ (the white thing) ??
