If you parent your character to the armature with empty groups and accidentally assign two or more bones to a vertex group, it will shrink or grow if you move it. To fix this, you can delete all vertex groups by:
- Click on Object Data Properties (upside down green triangle)
- Click on Vertex Groups
- Click on the black box below the minus or subtract symbol
- Click on Delete All Groups.
After this: - Click on Object (next to the mode switcher)
- Go to Convert and click on Mesh.
- Parent your character or object to your bones again
-
Carefully assign the bones
For Voxel characters, just use these steps on one part of your character that’s shrinking or growing.
