I have Silhouette which includes Particle Illusion and Mocha Pro.
-Since Mocha does easy and amazing camera solving and:
-Since Particle Illusion has 3d space (but fussy to work with)
It would be nice to import the FBX Camera from Mocha to Particle Illusion.
This could be a nice pipeline for basic particle effects.
(seriously the 3d setup in PI is awkward)
