The Config for the pm73rak uses hiddenselections "camo" while the modelconfig only defines the section "zbytek", meaning the vanilla config does not use a hiddenSelectionsMaterials or hiddenSelectionsTextures which can lead to confusion when modders try to reskin it.

Suggestion:
use

		hiddenSelections[]=
		{
			"zybtek"
		};

in config class of PM73Rak_Base
( I was able to reskin it that way )
