NoAttach tag

[Randazzo]

In Unity, I want to use the NoAttach tag on certain colliders. Much like the IconHidden tag, it is necessary to create it as user defined in the layers. However, NoAttach doesn't show up as a tag, only a layer, and it does not appear to actually work in game as the surfaces allow attachment to themselves.

Am I getting the syntax wrong or does it need to be a certain layer? 

Hopefully there's still somebody around familiar with it.

I figured out the problem! It was me.
