As the title suggests, if there is an instanced mask, then making an instance or copy of the decal does not also instantiate the mask.

So, you have for example a VRayDecal with a Checker as a mask and when you instance the decal the checker texture is not an instance? I may have misunderstood, since this works as expected on my end.

Yes that’s what I mean…odd that it works for you.

I have around 15 decals and I wanted the same vray colour instanced in them all, but it doesn’t work for me…I have to drag it back in and instance it each time I make a copy.  
Maybe it’s the Vray colour…I’ll try with a checker when my sequence finishes.

Seems to work with VRayColor as well. Isn’t your mask node name identical to the original VRayDecal’s? Or a copy of it is created for each instance of the decal?
