Unticking Show Viewmodel doesn't actually hide the viewmodel.

Apparently changing to color or material for viewmodels is impossible now. You need to find out a workaround to get it to work, and so far I haven't found anything.

Same here. When I talked to a fellow SCK user about the topic when it was brought up in casual conversation during some typical Zombie Survival gameplay, I mentioned that the "Show Viewmodel" tick box turns the viewmodel red instead of hiding the gun. The fix he proposed involves editing the alpha values and not RGB.

So if I'm not mistaken, all that needs to be done to fix this is to make it so that the SCK "Show Viewmodel" tick box makes the weapon's alpha values turn the weapon invisible and not red.
