I'll look into that. I hadn't heard of it, which is kind of the point. Poser isn't getting the same mainstream support in the stores for it's PBR system. I'd have happily paid for various hdri lights and even shaders. The offered Poser shaders/materials aren't for poser's PBR system that I've seen, but the same types of product for Studio includes PBR options.
