I'm currently trying to make a character model for Crusader Kings 3, but I'm struggling a lot with exporting the rig I'm using, as the rig contains groups, which the exporter seems to not like. Basically, my character has oval eyes, so I'm using a group to handle the transformation of the eyeball bones, while the bone stays at the origin (0, 0, 0). It means that when I rotate the eyeball bone, it'll rotate around itself, instead of rotating the entire eyeball. Image 1 is using groups, image 2 isn't
If I export with this however, I get an error saying that the eyeball bones are being ignored. Is there a way I can fix this, or will I need to go a different route for rigging the eyes?
