apologies for anyone who knows how to do this, but for those that don't....
please read on:
I've noticed in the past that there has been a request or two for applying decals on top of textures.
I've had a bit of time on my hands .So i though i'd look into this.
Please check out and play with the attached stacking texture file .orbx
This is using the newly introduced mix texture node.
I'm still using 1.55 standalone so the file is based on this.I assume that it will work on V2.0 and the plugins, but you'll have to test it.
once you've opened the file , try moving the tag and Mr Pettys Poster around the wall using the two sets of coordinate nodes.
Hope this helps someone.
See also the Screen shot for reference.layering note
The further down the tree towards to obj , the higher the Z stacking order of the decal.
