Here’s another reason why you might not want anti-aliasing on your ToonID (aka ‘Clown Pass’) render, as explained by Photoshop plugin maker Peltmade…
“for best results, make sure you don’t have anti-aliasing. This makes it easier for MultiFill to paint the white areas in your image.”
They’re assuming here that you’re working with Photoshop and their comics flatting plugin the old way. Scanned hand-drawn lineart, and then you manually make colour flats from that by painstakingly using the Paintbucket.
But with 3D renders from Poser you already have the colour render and also (ideally) a ToonID render in your layer-stack. If you then Paintbucket into the ToonID render when it’s in Photoshop, and the render is anti-aliased (i.e. ‘the jaggies’ are smoothed out, which is not normal but is possible if you do it a special way or blur it), then you’ll likely get some fringing at the edges of each of the colour wells.
Most of the time that should not matter for 3D comics makers, as the lineart you lay on top should be thick enough to cover those fringed edges. And you’re likely filtering a colour layer anyway, and the filter will smush any edge-fringing. So will the blending going on in the stack. If you’re only using the ToonID for area-selection with the Magic Wand + Smooth, then it also doesn’t matter.
If you chop or filter the lineart in Photoshop, such that the colours-edge beneath is revealed, it’s going to be a problem to fix either way. Best to get it as right as possible in the original 3D scene setup.
Adding to the line-art is not a problem (i.e. adding missing bit or lines, or chips in lines, even erasing and re-drawing simple toon eye-brows). But cutting it away or cutting into it would be, in this sort of situation.
But of course, now you can use my new Poser discovery to effectively get pseudo colour-flats within Poser and in real-time.
