So far, I've "exported" 3 scenes created in PoserPro 2010 to LuxRender via Pose2Lux. This programme promises great things, the most important being opening Poser user's views to consider alternative render options to Firefly: they are out there! LuxRender is but one of many.

My workflow has been typically this (no different, really, to what I already do): go first into the material room after everything's been set up and posed before invoking Pose2Lux. You will find that most of your materials need simplifying. About the only node that seem to have much use at this point (and I'm happy to be corrected on this by ThoseThatKnow) is the ImageMap, preferentially connected to the Diffuse_Color channel on PoserSurface or the Bump channel. Those two give the most consistent results. Actually, no idea where bump really plays much of a role, since the Pose2Lux material presets may affect that... don't know. There are still several unknowns about what actually comes across and what doesn't. Safest bet seems to be: get the ImageMap right, and chose your materials from what Pose2Lux has to offer.

So, now to have a closer look at the current list of materials in Pose2Lux.

Oh, and current render (5 hours in):

Monterey/Mint21.x/Win10 - Blender3.x - PP11.3(cm) - Musescore3.6.2
