Rigify Addon Version
Short description of error
Rigify addon built the horse part anatomically incorrect. Hind leg is missing an important joint at the lower hinds. Forelegs and hindlegs are built the same way in that area. See screenshot sketch.
Trying to fix the issue myself didn't work/resulted in advanced rig not being creatable, trying to fix in the advanced rig is beyond my knowledge and understanding, screwed up the tweak bones, bone relations, rig was completely broken. Nobody else on the Blender Discord Server could help me with this, either.
Exact steps for others to reproduce the error
Open up a new file. Import the horse rig. Enter edit mode. Subdivide the toe legs on the hinds and pull them to the same joint height and angle as the forelegs.
Advanced rig creation will fail.
This is NOT a feature request. It is a report to fix this malfunctioning bone setup that cannot be fixed by an average user. People cannot properly work with this! I've asked dozens of horse people and searched through sources and all agreed with me that there indeed is a joint missing where the hind fetlocks of a horse would be. Just like it does already have a front fetlock, it also does have a hind fetlock. See resources. Please fix this. It might be easier for the addon developers than someone who doesn't know how to change the addon properties at all.
