You can copy current material with selected index from model by Reload.

Models with multiple skins can have different set of materials for each skin (other indexes), e.g. same part of model with skin 1 can have material 0, but in skin 2 it will have material 3.

There are no problems or bugs with the addon, here is the video proof I made today. I remind you to press E+R at the same time.
You don't need to remove the bind on the scroll button. Tested on standard gmod without anything.
