Apparently CrochetPARADE Remesher can handle generating crochet instructions for 3D models that are NOT water tight, i.e. 3D models that have holes/openings. The Remesher was not designed for that as it does not support turning chains, yet even with rounds it can produce not-so-bad crochet instructions. See the example below:
Starting with an STL model with a hole (this is the STL model for the baby bootie demo from CrochetPARADE, exported from the new Export STL tool):
Remesh using the Remesher:
Render resulting instructions in CrochetPARADE:
(The glitches in the periphery should be avoidable if one plays around with the Settings and/or after a simple reworking of some of the internals, but for me, it's overall a good start, given that I did not expect this to work even this well at all!)
