Usage

Generating the Rigify armature

  1. Import a VRM model by going to File > Import > VRM:

  2. Select the imported armature object in the outliner:

  3. Go to Edit > Operator Search... or press F3:

  4. Search for Generate Rigify armature for VRM model and press Enter:

  5. The Rigify armature has now been generated! It will appear as Armature.rig in the outliner:

    Note that location of Armature.rig and Armature.metarig in the outliner may differ depending on the last selected collection.

Parenting the meshes to the armature

  1. Expand the (now hidden) imported armature object and select the meshes inside it:

  2. While the meshes are selected, select the generated Armature.rig Rigify armature.

  3. Right click and select Parent > Armature Deform:

  4. The meshes should now be parented to the new armature. Expand the contents of the new armature object in the outliner:

  5. For each mesh, under their Modifiers, move any armature modifiers to the top of the modifier list, before all other modifiers:

    You do not have to do this if there are no other modifiers present.

  6. You can now pose the model by entering Pose Mode:

  7. (Optional) Remove any objects that are no longer needed:
