Decals and VisRegions

[DoobesURU]

A small but noticeable bug when working on Tiam:

When an object has both a decal (for footprints, for instance) and a Visibility Set attached, it causes the decal to not appear. Perhaps we need an error thrown when these two modifiers are used on the same object?

EDIT: In further testing, this only seems to affect MOUL, not PotS/CC.
