$nodecal Only Works on First Skin for Models

[Helghast-Loyalist]

Details

$nodecal is only respected for a model's initial skin. If '$nodecal 1' is set on a model's initial skin, other skins that should accept decals do not, and vice versa.

Steps to reproduce

1. Add a skingroup to a model that points to an identical texture but with a vmt that has $nodecal
2. Attempt to paint a decal on the model with skin applied
