Rigify Problems - Please Help!

Please help, I have to submit this animation in two days.

I had this message: can’t add new bone ‘root’ outside of edit mode, incorrect armature for type ‘ utils’. I read another thread and saw that all I had to do was rename the rigs but now when i generated, this happened

The rigs merged together and now I’m stuck
Please help

It looks like you are having scaling problems, in addition to the rigs merging. You should be able to separate the two rigs by renaming them again. Get rid of your generated bones, rename the rigs to something like skinny_dude_rig and buff_dude_rig, and apply scale and rotation to both the meta rigs and the mesh before you generate new rigify rigs.
