Occasionally I get to work on research and development efforts at Vectorform, and a month or two ago posted a video online of a crumbling wall. Originally created just to test Lightwave 11’s fracture modelling and bullet dynamics integration, I ended up adding dust effects in post using Trapcode Particular, along with other effects and grading.
The video was noticed by Mr. Norrby of Trapcode (@rymden), who passed it on to Mr. Rabinowitz of Red Giant (@RedGiantNews), and the quick proof of concept ended up getting turned into a video tutorial about compositing Particular effects using rendered depth maps! Watch Red Giant QuickTip #67: Realistic Dust Hits to see how dust effects in After Effects can be seamlessly integrating with rendered footage from any 3D package.
