Adjust metarig

Edit metarig armature, let it fit to your character mesh.

adjusted metarig

Set vertex group for armature deforming.

GameRig will copy bones without renaming differs from 'rigify', you can test armature deforming with metarig armature.

setup vertexgroup

Add additional bones

If your model has hair / cloth / etc. bones, add these too.

These bones will be copied to generated rig.

If they have constraints and/or have drivers, these will be copied too with right target.

Regenerate rig

If you feel some bones have bad positions, it means you need to edit metarig again, but you can regenerate rig quickly after edit metarig.

Edit metarig again, and click 'Regenerate rig' button to apply changes.

regenerate

Note:

Please confirm current collection contains target rig to overwrite.

Otherwise, gamerig generate a new rig to current active collection.

wrong collection

Deference from Rigify

Clean hierarchy

GameRig dosen't rename original bones and dosen't add deform bone and dosen't insert any bones to original bone tree.

More suitable for game / VR content development.

Multi Face Rig

More flexible face rig.

Blend animation and physic simulation result

'generic' and 'tentacle' rig can blend between own result and metabone's constraint result if metabone have constraint.

Tips

How to use with an existing armature

An armature not recognized as GameRig's metarig, the armature's properties panel has no GameRig panel.

Then you cannot setup metarig with existing armature.

no gamerig panel

In this case, add 'Single Bone' metarig and join (Ctrl + J / Menu Object→Join) an existing armature to it. And remove 'root' bone from metarig if you don't need it.

add single bone

Gamerig panel will be available in armature properties panel.

joined armature

In pose mode, you can set rig parameter in GameRig Rig Type panel that be placed on bone properties tab.

edit rig type

Why 'Unity Mechanim/Human' metarig has X 90° rotation

By deference of coordinate system between Blender and Unity, imported mesh lie down in Unity with a fbx file exported by Blender. This is a reason of metarig has X +90° rotation (GameRig generates a rig with same rotation as metarig).

imported fbx 1

Rig armature having X +90° rotation and their children having X -90° rotation, and settings of export fbx are:

  • scale is 0.01
  • 'Apply Unit' is off
  • 'Apply Transform' is on

and Unity side import settings are:

  • Scale is 1.0
  • 'Convert Unit' is off

parent has x +90° rotation child has x -90° rotation export setting import setting

These settings make imported fbx object having right orientation and clean transform (no rotation, no scaling) on Unity.

Note:

For combination of Blender 2.80 and Unity 2019.1

I was using deferent settings for same effect in Blender 2.79 and Unity 2018.4 era.

no rotation and no scale
