I just upgraded to Poser 11 (not pro) recently and I'm trying to come to grips with the new physical surface shader node. There are a few things that I have gripes with but one thing at a time.

OK, so, imagine a simple sphere and a flat plane in front of it facing forward. I've created a texture for it with simple PBR textures and a transparency map. When I render everything out with all the maps connected properly to the PoserSurface node then everything looks fine in both Firefly and Superfly. However, when I plug in all the textures to the PhysicalSurface node then everything behind the plane gets tinted the colour that is mapped to the plane EVEN if the transparency map shows full transparency for parts of that plane.

The crux of the issue is: PoserSurface node = transparency correct PhysicalSurface node = colour tinting on even completely transparent parts of the mesh

What I want is to have complete colourless transparency on the PhysicalSurface node.

How can I achieve this?

Thanks in advance.
