This thread is for known problems with the Make Human Blender Community Plugin, specifically with the rigify feature set. I posted many months ago, on an unrelated thread, that the rigify feature set has a few errors. I will post here for better notice. Please feel free to add with problems you have discovered with the rigify feature set. I am using the latest stable version of Make Human, the latest MH Blender Community Plugin (for rigify feature set), and blender 2.83.13.
The first problem is that the rigify rig cannot be named before creating the rig. This is a problem as without the ability to name it, you cannot append multiple rigify characters into the same blender document without their Rigifiy User Interface scripts running into each other. I create the characters but since all their widgets are named the same, it confuses the rig ui python script when multiple rigs are in the same blender document. Only the first rig actually gets the needed user interface this way. The manual way of creating a rigify rig allows you to name the rig before creating it. This gives are unique name to each widget, the user interface script, and where they correspond in the ui script. It would be nice if the MH Community Plugin also allowed you to name the rig using the same idea as the manual way. It could even use the character's name in the MH metadata for added integration, but that is just extra really.
The other problem I have encountered is the automatic rigify creation by Make Human puts the breast bones on the character's back instead of their front.
If you have found additional problems feel free to add them to this thread.
I am overall pleased with the feature set as it does many and most things right. Unfortunately I cannot use it in my workflow yet because of the multiple rig UI's causing problems when in the same Blender document. It will save me much time to get this resolved.
