Did you ever get around to adding support for
https://hub.virtamate.com/resources/video-and-image-renderer-for-3d-vr180-and-vr360-and-flat-2d.11994/ ?
I remember trying them both on an old version of the plugin and it flickering when you activated the camera, haven't tried again since.
hmm, how about a way to add genital normals to it, I tried converting a normal map into a bump map but it didn't seem to work with the bump, or maybe I screwed something up, is this possible?
