The plugin conversion was developed before there was a physicalsurface root node (P11).
It would be nice though if this root node in Poser was translated to metallic or universal material.

I think it could be converted from the current code, because we'd just have to change the root node ID string, the channel ID strings, and then matching the node connections because they are different. In addition, the Physical Surface node has way less channels than Poser Surface, so it should be less work in the conversion. I think it's worth because the world works in PBR these days, and newly created materials are all converging to it.

So far, everything appears to work nice!

Within the image nodes (Greyscale or RGB ... ) we now have an option called "Linear Space Invert".
By default is enabled, but what does it do, please?

I'm sorry - I cannot recall the specific use of this pin. I suggest asking in the Octane Standalone 2018.1 release thread.

Thanks

It has been years since my materials have all become PBR-based. Won't the Octane plugin support at least the Physical Surface root node?

Happy to provide a conversion from the Poser PhysicalSurface to the Octane Universal material if you can provide the conversion rules (ie. what each of the PhysicalSurface parameters convert to on the Universal material - and what the formula is for each of those conversions).

Fair enough. But considering Cycles is open source, wouldn't SMS provide that information? Or perhaps it could be mapped to Cycle's default Principled shader, which generally aims for the same results?

I'm not sure - sorry. I am just saying I am happy to make the changes to the plugin if you detail specifically the rules you want coded.

I see. Just tell me what you need and from whom, and I will try to get it for you.

You said you were only using PRB materials in Poser - so what conversion rules do you use for converting this materials to Octane materials.
