So when I import a material built in one scene into another, I am unable to edit or even see the node.
In this case, I used a material preset I had on hand and placed it on a sphere. I simply 'dragged' the sphere into a new scene. The resulting material node changed from "Nylon Weave" to "Mask024". Further, when I click on "Mask024" I don't see it show up in the node editor. I can't seem to find this node tree anywhere and it becomes a dead material.
I am thinking it's a bug..
I have a much more complicated file that has 20 or so materials that I'd rather not have to re-edit/re-build if possible.
