Creators who need to ensure their avatar works perfectly in commercial VR applications.
A: Yes, there are some free tools. For example, the command-line tool modelconv by m-shimao can convert GLB to VRM.

A poor conversion process can introduce a variety of technical glitches that ruin immersion:
Facial expressions don't work. Solution: Ensure blend shapes have been assigned to the correct VRM expression names (Joy, Angry, Sad, Surprised, Blink, etc.). In Blender's VRM addon, open the Blend Shape panel and map each shape key to the appropriate VRM expression.
Facial expressions (mouth shapes, blinking, eyebrow movement) are stored as shape keys or blendshapes in GLB.
