Just a quick question regarding Retargeting BVH to a WGTS rig.

I started using Blender this Feb and im having a lot fun learning what it has to offer.

Question : Is it possible to Retarget from BVH to a Rigify generated Rig ( WGTS_rig as it says when i generate it) ? I tried doing that to deform bones in hiddenlayer but it doesnt seem to work as these are locked by constraints.

However i can successfully retarget BVH to a metarig… but i was wondering if its possible to retarget to rigify rig and if so how. I tried looking at topics in forum and most of them seem to be 5 years old on this. Is there any latest workflow for this?
