Sandy3D, a few questions

Hey All -
I’m not sure how many of you all have worked with Sandy3D thoroughly enough to answer a few questions that I have, but I’m working on a small project, testing the functionality of the API, and I’m running into a few walls… or at least some upramps that will eventually tend to larger problems. lol.

Here’s an example of what we’re working with, here:
http://www.2200designs.com/testingCman2200/testingGrounds.html

Its essentially the background of this site. The clouds are 2 plane3D layers, semi transparent, and each with separate Tweeners for motion to simulate cloud motion. The method I used to blend the background and the cloud floor was a smaller plane with a blur (is there a better way to do this?! I’d Realllllly like to know). The camera pans and tilts with respect to them mouse’s position (later functionality justifies this extra effect).

Now with all of that, my project struggles to maintain anymore than 16fps… which is fine because that’s my goal. But there are quite a few different things I’d like to add as well, and that means more 3d objects, more animations, more math, and thus, lower framerate. So are there any people with some prior Sandy experience that may be able to help with some ideas on improving frame rate? or any ideas on how to better or more efficiently express what I have so far?
