This is another attempt of mine to make Trapcode Form particles respond the main composition camera motion. So they act almost like 3d objects as you see. The trick is in connecting precomposed particle camera to main composition camera plus some more little tricks added in this version. Particles were created in AE as well.
Unfotunately it's not possible to use Textured Polygons and Shading with this because these options make particles distorted for some reason (probably because the precomp is used with transormation collapse flag).

Another disadvantage of this is that it is not possible to use multiple particles source, at least i havent found the way to do it (yet). Since the main comp and particle cameras are connected in time it doesn't let me use Time Samples to their full. I tried to trick it by creating 2 particles (with some variations) in the same particle precomp (butterfly) with camera connected to main but with scripted time offset using Split Clip mode, but it didn't work.

For this version i used a pair of butterflies in one precomp with slightly different positions and motion parameters.

Hmm…it looks like things are taking a while to load. Try again?
