Take, for instance, a short sleeve shirt where the outer edge of the sleeve can be seen against the arm. The goal here is to give the shirt a basic sense of existing in 3d space rather than being able to see that it’s a warped 2d plane at the edges depending on view angle.
I’ve picked apart a few models in c4d to see how othes handle this, and seen a few approaches.
Some, for instance, create extra edge loops, then offset them in toward the arm a bit, and fold them back like an inverted cuff so the viewer sees a slightly rounded 3d appearance to the edge of the sleeve as it disappears back toward the arm.
That’s more or less what I’m doing currently, but wondering if there’s a better option. For instance, is there a way to take a complex mesh form (using example of shirt), and create an automatic extrusion of it that extrudes not along an axis, but inward or outward depending on the contours of the object, then uses caps or bevels or something to define the thickness and edge characteristics? (create 3d “solid” from 3d mesh).
