Adding Shapekey Category Option to Transfer Shapekeys

[Maneki]

Currently there’s only a “body part” option for transfering shapekeys. A nice QoL improvement would be to also add a shapekey category select option. When I import favourite morphs for example and want them to transfer to geografts and face meshes, I could quickly select all these freshly imported shapekeys.

I’m not sure myself why there’s “face body custom“ when we load morphs, probably this is ancient code before we had categories ? I don’t think the transfer tool makes any difference since it uses boxes then vertex maps to delimit the influence area iirc. Thomas let us know.

Recovering the categories from the shapekeys is not straightforward, although I suppose it can be done. However, if you goal is to transfer new shapekeys only, you could just disable the Overwrite Existing Shapekeys option. That should speed up the transfer a lot.

Ok thank you. What I understand is categories are intended for morphs, not for shapekeys, thus the simplified “face body custom“ selectors. To implement categories for shapekeys we would have to scan all the morphs and see what morph each shapekey belongs to.

If there’s nothing to add we can close as invalid or wontfix.
