Hey all!
I wanted to ask if there’s an automated way to match the Epic Mannequin template guide to my own character model that has the same skeleton hierarchy (and similar orientations) as the mannequin
any help would be appreciated!
EDIT: I changed the rotations so they’re planar btw
the script that match the metahuma is in this module https://github.com/mgear-dev/mgear4/blob/master/release/scripts/mgear/shifter/io.py
is the metahuman_snap()
it attaches to the _drv skeleton. You can edit it to your needs.

If anyone wants to take a gander themselves, here’s what I have so far, which wont really produce a good result just yet.
