Help Character Cloth with Final IK (with GIFs)

[VrTech]

This is how it looks without obiCloth
The cloth weight is transferred from the rigged character as I followed from the TrenchCoat Example.

*Final IK + Grounder has been used



Once I attached the ObiCloth this happens.



This is how I set up based on your tutorial webpage

Obi Solver on the Character Root
Obi Cloth on the Skinned Mesh Object

*Player Object is a root





Setting on the Animator on the root (Player) 

What I used
- Obi Slover
- Final IK FBBIK
- Grounder



This is the Script Execution Order



Please Help! I try to solve this problem for a week but I can't.
Thank you in advance!
