I like the suggestion and it was actually something I tried to put into the original RealSkinShader 10 years ago. However I always have more questions than answers on how it would be implemented. Which settings are referring to? Just the Octane imager, kernel, camera settings, or "others"? If it's "others", what are they? Saving a template for the Octane render settings is trivial to implement, but I get the feeling you want lights added, etc?
I wonder if this requirement would be better served by creating various poser props which would act as emitters, where you would save the Octane material settings back to the Poser Material. These props could then be loaded into any scene.
