I imported vrm avatar through vrm4u plugin. The retargeting worked very well except for the hair. I checked the spring bones were working correctly when I substitute my vrm character into the playable character in 3rd person perspective mode.
I’ve tried other motions which moving its head and it always shows that the ponytail is anchored in one position and stretches like a decently cooked mozzarella cheese stick.
I want to fix this problem. Is there any advice to fix it??
