Nomad, I've gotten animations looking good in Granny. So far. If he ever is finished I suggest making him very, very big to account for his slowness in falling when dying.
Nexus is where the men are separated from the boys. Granny is just the inflatable dinosaur kiddie pool; the adults are all swimming in Nexus. Almost every problematic import I have done looks great in the Granny Viewer and then promptly turns into a soup sandwich once I view it in Nexus .
