It looks like these weren’t even touched in 5.7, there are so many incomplete and broken parts, it’s really disappointing and frustrating to use.
For example, for all of the legs and arms, there is a parameter to set the secondary axis, which is really important so the limbs face the right direction when using IK. However, that parameter doesn’t actually set it in the rig module for some reason. You have to go into the module and hook it up yourself. WHY??? There are others that are the same way, they are exposed, but then hard coded in the module. It is really misleading to expose these and have them do nothing.
This is really terrible to have to dig around in everything just to see what isn’t hooked up, just to use modular rigs on custom characters. I hope this gets fixed by 5.8 at least.
