Anyone know why custom collections don't seem to work in the Renderpass Node? Is that a bug, am I missing something, or is this a "feature" (collections within collections)?

Often in large scenes we use collections in lighting to create complex groups of prims. It would be useful to pass those into various render passes, but although they show up in some of the drop down menus once created, they don't seem to do anything.

Any suggestions?

Ah, it looks like the coordinate system approach is karma specific. Someone let me know if I'm wrong.

I haven't tried the custom solution from Egert above, but I did implement the coordinate system set up that Tomek suggested. It works pretty well, but I'm wondering if anyone know why it doesn't show up in the viewport. It works perfectly once you start karma, but the viewport shows a weird tiled version of the texture. It doesn't make for the most artist-friendly set up. I looked into all the material bindings and don't see why the ndc coordinate system wouldn't be picked up by the viewport. Any help appreciated.
