I did all the particle work on the gun, gun blasts and the portals in ICE:

Honestly the setup couldn’t have been simpler. There’s a stretched sphere that acts as an emitter for when the gun shoots. All the particles it emits have an animated turbulize node on it. On the walls there is a disc shape that it collides with and spawns new particles – then there’s a ring they’re attracted to. The velocity and weight are also turbulized.

That’s pretty much it.

Everything was rendered with emRPC and sent over to Nuke for tweaking by the compositors.
