Of course I left out what could be the most important part - I emit a bunch of particles from a layer emitter (Z size large, creating a 'volume') on frame 1 at velocity 0 and then set my pps to zero, ending up with a cloud of particles not moving.
I would think that if the particles were all emitted at one time on frame 1 then there's no further simulation or re-evaluation with the scene, or in this case, the camera when it moves past, spinning on Z as it does.
There's nothing odd. Particle rotation like many others is a birth attribute defining the initial orientation. Otherwise your setup doesn't make much sense. If you bank the camera, you can just as well rotate the texture in the pre-comp to create the effect. Everything else works as the effect is intended to operate.
Hmm... I had tried rotating the precomp too and that didn't work, but now I know why - my Sprite is a comp with 50 1-frame images - my particles are set to Random - Still Frame. The only way I can get your suggestion to work is to set Time Sampling to Current Time, which I can't otherwise all of the particles are the same. So I was able to get the banking effect but don't have randomly selected Sprites.
Thanks for the suggestion.
Could it be that you're using sprites. The defining feature of sprites is that they always maintain their facing position to the camera regardless of where or what the camera does no?
Thanks - I think we arrived at the same place at the same time. I switched over to Textured Polygons and once I re-oriented the particles (they were edge on) I had my a) random images b) banking with the camera. Perfect.
But then, like any good game of Whack-A-Mole, I started ending up with particles that pop off when close to the camera. The dreaded Near Far Vanish. I have my Near Vanish set to ZERO (and Far Vanish/Start Fade waay off..) but particles disappear further from the camera than you'd expect them to. In fact, if I toggle back to Sprite - same visibility values - those same particles REAPPEAR and don't disappear until they've passed out of frame, past the camera.
Is there a Disable Clipping feature I'm missing?
