After several days of experiments, I've successfully proved that it's possible to 'render' from Poser using Stable Diffusion 1.5. By 'render' I mean that SD 1.5 should work like a usual render engine, by retaining exact outline registration with the Poser scene. This, and the fact that the final output (seen above) is 1024-pixels, enables easy masking of figure / background / props. As you can see above, a basic 'Canny' Controlnet has kept SD's image generation locked to the original real-time Preview render from Poser, while allowing just enough wiggle-room to 'render' in a new style (in this case, old-school comic-book).  The pockets and suit lapel are 'invented' by SD, true - but that's because they're not specified in the input image. And the final image is lighter, true, but that's because I lifted the brightness a touch in Photoshop. The starfield was added in Photoshop (Glitterato plugin), before the Poser Preview render was sent to Stable Diffusion.

Anyway, it is possible to 'render' using SD and retain exact fit with the Poser renders. I now plan to have a Python script output and name the needed Poser render set.
