I’ve finally been able to get back to my Poser to Stable Diffusion 1.5 experiments. More immediate success, this time by starting with a Brian Habelin style ‘darklight’ lit Preview render (very low single light, Comic Book lineart in b&w, textures showing through just a bit) and then a Firefly lineart-only all-lines render. Combine these two in Photoshop, and you deal with the dark suit and the lack of definition of the suit detailing, at the same time. Nice. Img2Img as before, with the Poser render also dropped in the Canny Controlnet.
Deliberately awkward M4 pose and hands on the Meshbox Lovecraft figure, and rendered at just 768px, to see how SD handles such awkwardness.
The 1024px result stays nice and light, and doesn’t immediately start veering into the grungy ‘black on black’ territory which bedevils 3D work. And there’s no need to lift the gamma or adjust textures in Poser. The contrast is easily adjusted later in Photoshop. There’s also more of a Eurocomics ‘ligne claire’ (clear line) look than my previous highly detailed Moebius attempt. I like this simpler look. Interestingly, SD is colourising without being asked to do so.
Quite a high CFG for this, so SD 1.5 had more room to wiggle. Which means both the thumbs have gone wonky, and the eyes have been adjusted to look away rather than up. However, everything else is locked and we still have the Photoshop-accurate layer registration otherwise. So one could colourise the result by layering a Poser render on top in Photoshop, and simply setting the layer blending mode to ‘Color’. This would give you a base of consistent colours from panel-to-panel in a comic-book page.
