Blender's bone constraints include options that allow you to select whether the constraint's axis is the local axis or the world axis, and transform transformation constraints (you can convert position input to rotation output, X axis input to Y axis output, etc.).

These are functions I would like to see implemented because they can be used to control more advanced operations from a single input.

For example, the attached file uses the Local Axis -> Local Axis Rotation constraint to recreate clothes that slide down according to arm movement.

Currently, in order to reproduce this in Unity, it is necessary to insert an empty object for axis conversion, and furthermore, since there is an axis that cannot be converted by any means due to a gimbal lock, it is extremely difficult.

Also, if transform transformation constraints can be used, the number of constraint components can be further reduced, so if possible, this is a function I would like to see implemented in addition to the current list of constraints.

Blender's bone constraints include an option to choose between local or world axis for the constraint, and a transformation constraint (i.e., position input to rotation output, X-axis input to Y-axis output, etc.).

These are features that I would like to see observed, as they can be used to control more advanced movements from a single input.

For example, the attached file uses a local-axis->local-axis rotation constraint to protective clothing that slips down as the arms move.

Currently, in order to propose this in Unity, it is replacing to insert an empty object to convert the axes, and there are axes that cannot be considered due to gimbal lock, making it very Expectations.

Also, if the transformation constraint can be used, the number of constraint components can be further reduced, so if possible, I would like to see this feature proposed in addition to The current list of constraints.
