Which skeleton to build. general (default) lets the model choose; humanoid/game bias toward anime-style and classic game-character rigs. The humanoid_template options pin a standard humanoid skeleton with named joints: humanoid_template (22 joints) or humanoid_template_hands (52, five fingers per hand). Only for two-armed, two-legged characters.
Bone naming convention for the joints we can identify. Purely a relabel - the skeleton is identical. Joints outside the humanoid template keep their generic names.

Re-rig - save the rigged result as a new 3D asset entry instead of overwriting the source, preserving the original model and its saved animations.
