Open your avatar project in Unity
Import the glove Blender model and the VRC SDK if needed
Make sure the glove mesh is in a supported format, usually FBX after export from Blender
In Blender, position the glove correctly on the avatar hand
Apply transforms in Blender with Ctrl+A
Export the glove as FBX with armature and mesh settings as needed
Drag the exported glove FBX into the Unity project
Select the glove object in the Hierarchy or Project window
Parent the glove to the avatar hand bone, usually RightHand or LeftHand
Adjust local position, rotation, and scale so it fits the hand
If the glove has bones, ensure the glove armature is properly parented to the avatar armature
If the glove is static, keep it as a mesh parented to the hand bone
Add or verify the avatar has a valid VRChat Avatar Descriptor
Check that the glove is inside the avatar hierarchy
Make sure the glove does not exceed VRChat mesh or material limits
Assign materials and textures correctly in Unity
Test the glove in Play Mode or with the VRChat SDK avatar preview
Upload the avatar through the VRChat SDK when everything looks correct
