I have been looking for a simple way to get a rig using Rigify that doesn’t have a „destroyed“ deformation bone hierarchy since some time. Like that IK animations would become possible just with the generated rig for the usage in game engines.
A few days ago I was informed that the basics for such a solution can be achieved by the modification of a single line of code! It means that the ORG bones are used for the weight painting instead of the DEF bones.
We decided to work together on that topic and communicate in an „open“ way in this forum.
Our goal is that our changes are finally merged with the offical Rigify code. The user should be able to decide, if the default rig should be generated or the game rig. That may be done using a checkbox or another button. (e.g. „Game Rig“ checkbox or „Generate Game Rig“ button.)
That’s what we have so far. Let the discussion begin
