@Rhia474 When you convert Poser Surface materials to Physical Surface using my script, it has an option to "Use Image Maps Only", which means it will bypass all Firefly shader nodes and use only the texture maps. I believe this option is enabled by default, but if it's not, give it a try.

Having that said, this has a catch: some materials use procedural textures (shader nodes) instead of textures. In this case, the option above will result into blank materials. If that happens, try disabling the option and try again. If the render is still black, it means the Firefly shader nodes are totally invalid in Superfly with Physical Surface, and might need some manual editing.

It is important to remember that "Go Physical" is meant to create a PBR base material out of Firefly materials - it is not a FF to SF material converter. It does its best to automate the process as much as possible, but some cases might need some manual editing. It cuts a lot of time on the tedious part, and lets us go straight to the editing fun. :)
