I'm finding it impossible to generate my model's rig so I can animate it.. I've positioned the metarig twice now, re-imported the model as a much lower poly-mesh, checked the mesh's integrity and looked for any detached parts that aren't meant to be detached, and hid the separate meshes from the scene; (which I need visible and unattached for the animation); and it still throws this error.
Every tutorial I've found and followed waits until after the rig's generation to parent the rig and the mesh, but I did try doing that before as well. That resulted in just the circle with arrows at the model's feet, but no actual rig.
The only bones I deleted from the metarig are the face bones, and the only other edit I made to the metarig was for one of the spine bones. Before the NoneType error, it gave me an error that one of the spine bones was disconnected. In order to get that to work, I had to parent the ends of that and the bone it should have been parented with together.
I don't know what to do at this point. I've been bashing my head into the problem for going on 3 weeks now and have made 0 progress. I'd really appreciate some help.
