HAT help

hey. My name is Rick and I need serious advice and info about HAT. I’m not sure if the topic has been posted, but I have serious onion skinning problems whenever I animate through the program. Usually the “ghost” skins will disappear when I play the clips, but most of the time they’ll just stay during the duration of the animation as scene here:

…i was trying to recreate the Paul Simon vid “Call Me Al”. Also sometimes the skins glitch and vibrate, making it a bit hard to pose.

so if anyone can help a GMod newb out, that would be nice. Thanks!
