I've been using the Trapcode suite for a few years now but its been for mostly 2D motion graphics type things, I saw a Behinde the scenes video of a corridor digital video called "Ultimate gun game" where there VFX guy said he had built a 3D enviorment for particular to interact with, theres a very breif clip of him demonstrating it but I am stumped on where to start. Anyone ever do this ? (Ive included the video with the start time)
Look in the Trapcode Particular help file for information on the Physics parameters - specifically, the Bounce options (as opposed to the Air options).
You would camera track your scene, use the camera tracking tools in AE to make solids (or nulls) in appropriate places. You'd then add the solids you would want Particular to interact with based off of those (usually requires a bit of tweaking to get right).
