Check your humanoid bone mapping configuration. Ensure left-hand finger bones are not accidentally mapped to right-hand slots. Additionally, ensure the thumb bones follow the proper rotational axis relative to the palm.
如果你有编程基础，使用开源库可以获得最大自由度和自动化能力：
Requires account signup; might not handle complex custom animations or specific bone mappings as well as manual tools.
What are you trying to use the VRM in (VRChat, VSeeFace, etc.)? Is your model already rigged (has a skeleton)? convert glb to vrm fixed
“The eyes are floating three meters left. The rig has 47 unnamed bones. The blendshapes are there, but they control the left toe instead of the eyelids.”
When you force a standard GLB file into a VRM container without proper mapping, applications cannot read the skeleton or expressions, resulting in a broken avatar. Step 1: Prepare the GLB Model in Blender
The shift towards virtual identities has made VRM the standard file format for 3D avatars. While many models are created in format due to its efficiency in storing textures and geometry, VRM offers crucial features for virtual characters, including: Pre-configured VRMSpringBone (for hair/clothes physics). VRMBlendShapeProxy (for facial expressions). First-person rendering settings . Check your humanoid bone mapping configuration

When you use a basic online converter, these specialized layers are stripped or poorly auto-generated. This results in standard glitches like dead eyes, rigid hair, broken joints, or completely transparent textures. The Ultimate Fix: The Unity and VRM UniVRM Method
To achieve a perfectly fixed conversion, you must use Unity paired with the official UniVRM plugin. This environment allows you to manually correct the skeleton mapping, configure the shaders, and apply dynamic physics. Step 1: Prepare Your Environment “The eyes are floating three meters left
User must manually assign bones and expressions from a list. Access: Available on JustinBenito's GitHub . ⚠️ Common "Fixed" Issues to Watch For
If you have ever tried to drag a standard .glb file (a common 3D format for games and e-commerce) into a VRM-ready application like VRChat, VTuber Editor, or Unity with the UniVRM plugin, you have likely seen the dreaded red error text. The model looks "wrong." The eyes don't blink. The bones are twisted. Or the import simply fails.
A "fixed" conversion means the model works perfectly in VRM-compatible software: proper facial expressions (BlendShapes), correct bone structure, specialized shaders, and correct "look-at" behavior.
