H21 AutoRigBuilder Issues Oct. 28, 2025, 8:52 a.m.

i reparented the twist joints as you suggested and it works now...
the arm and legs are created right.

but i dont know how to map the existing skeleton twist joints to the autorigbuilder-twists...
creating additional mappings i.e. "upper_twist_01" to "my_custom_twist_01" does nothing and rotating the hand controller also does not perform a twist on the created nulls from the autorigbuilder...

any suggestions?

thx for the fast reply.

indeed, the maya skeleton (mgear joint skeletons) is in maya units and scaled down with the "convert units" from the fbxcharacterimport.
also the twist joints are in a continous fk chain (joint01->joint02->joint03->etc).

i updated to 21.0.512 and try out your suggestions to see if it solves the issues.

with this update, a 3-point-joint-skeleton seems to work now with the autobuildrig (also i switched to opengl viewport, and it also seems to update correctly. before there where viewport-update glitches...)

Hi,

i have a fbx from maya with a fk skeleton structure, where also inbetween twist joints are present (legs + arms) for deformation.
when setting up the "new" APEX autorigbuilder and want to use the leg (or arm), it always highlights the first 3 joints in the leg joint hierarchy (and not the first, middle and last)...
in the "build" tab i can remap to the right joints, but then the final rig is not constructed right, the controlls are way off and the deformation is destroyed, the leg gets stretched...

i also tried from scratch with a houdini skeleton (with fk twist joints, and with 3 point joints) and it also not working...

does somebody know how to deal with that kind of pre-existing fk twist joints from other DCCs and autorigbuilder?
also is there some info what kind of remap names (from->to) the autorigbuilder uses?
