Smooth camera transformation

I was wondering how to get a smooth camera transformation going. I am trying to have the camera orbit an object while following it (non player object). I am not using the advanced camera, etc - just the stock camera (i rather not change to the advanced one).

I'm setting the camera transformation to follow a certain distance in orbit mode. I ran into a similar choppy problem transforming an object around - that was because the client wasn't being updated by setting the mask bits.

This time it seems to be setting the mask bits, but the camera still chugs around. Any clues? Thanks!
