Indeed! The real deal with Octane is when we start using its own materials. ^^
I can tell the HDRI projection is not right here. This is cylindrical or spherical, but was rendered as planar. This will definitely affect the lighting. You can change the projection type in the parameters.For some reason I could not get the orginal HDR of the posted a couple of pages back to work with Octane, not the lighting just getting to line up correctly seemed impossible. So here is a variation on the theme with the HDR in Octane and no lights.
I keep saying that PBR rendering makes more sense than biased rendering like FF and 3DL. The lighting, materials and cameras use real-world parameters that make sense, especially if you understand photography jargon. There is also the fact that you don't have to fake AO and color bleed with extra lights, extra shaders, and extra rendering parameters - all of these are handled automatically in Octane. The bottom line is that PBR rendering produces predictable results, as opposed to how it is with FF/3DL. Getting instant refresh in Octane is also a breeze to work with, because this tends to be the MOST time-consuming part with other renderers. ^^The material database on line is quite extensive but I also like the fact that the default material can be modified and copied with relative ease. Maybe it is just me but the materials also make a lot more sense than the nodes in Poser's material room, such as adding and controlling emitters or adding a sheen are all straight forward and logically named. Where there is something I do not understand the explanations given by floating over the parameter is precise. I am only scratching the surface but I do like it a lot so far and you have the added advantages that you can see changes in almost real time and you are not affecting the Poser scene if you wish to revert to Firefly or Superfly. There is so much more to learn but to be able to come up with pleasing results so early in the learning curve is encouraging.
