Hi, Krewz --

Glad I could be of help.  I don't have V4 yet so I'm not familiar with the bending magnets, so this may be an ignorant suggestion, but that rarely stops me!  Is it possible to select the V4 character and the bending magnets and group them?  That way you'd be able to collapse her into one line on the hierarchy.

And as for real-time playback, it's been an adjustment to test render each shot a number of times, but since I go 'way back to the old days of stop-motion animation on film, where you didn't get to see how the motion looked until you got the film back from the lab, it was a fairly quick adjustment for me! 

Carrara's renderer is fantastic and with plug-ins like Digital Carvers Guild's toon!pro and wireframe pro, you can get some really cool cartoon results that I've not been able to get from Poser itself.  I bring that up just because Carrara does open a wide variety of options once you're using it.

Good luck,
Dex
