A viewport render from my smoke sim. The shot opens with Fisher opening up the box (he hasn't been animated yet) and the smoke columns shoot out and land. The Shadow monsters haven't been simmed out for this shot yet and they won't be visible until the smoke hits the ground.
Massive is going fairly well. I am pretty comfortable with my opening town sim when the townspeople are just milling about. Other than the one agent that decided to stop, turn directly towards the camera, and wave for about 30 seconds, the agents behave as expected. The "panic" mode part of the sim isn't perfect yet. They tend to ignore the painted boundaries and run right into the water or through buildings.
