Not sure what the problem is here. I had my fur just as I wanted it and then applied a rigify armature only to find that my fur thinned out. The rigify armature works perfectly and I did not make any chnages to the particle settings. But for some reason when I chose to render the fur after installing the rigify armature, the fur appears thinned out. Here is a sample of the fur before rigify and after on a tail. I would really like to find this myself. Does anyone have any ideas on what may be causing the problem? I know applying an armature, either custom or rigify, should not affect the particle system especially in rest mode.
I checked all particle settings before and after installing the armature and they are the same, I also experimented with the modifier order with no results except a slight change when I moved the particle modifier between the sub surf and the armature modifier. By the way my armature is above my subsurf in the modifier stack. Anyone have any ideas?
