In the ongoing open beta test, the automatic conversion from Unity Constraint to VRC Constraint is enabled by default.
However, as you can see from the Open Beta Board, there are still many assets that break due to behavioral differences when converting automatically. (e.g., VirtualLens2 by me and Camera Path by DX.)
As an asset developer, I intend to provide updates that support VRC Constraint as soon as possible, but reflecting these updates will require users to re-upload their avatars. Therefore, it will take some time for the updated versions to become widespread.
Could you please keep the automatic conversion disabled by default until sufficient compatibility can be ensured or until some time has passed?
