I have a scene with a camera that flys up to and through a particle field. My issue is that rather than flying offscreen as the camera travels through them, the particles dissapear at a certain distance from the camera. They dissapear when they're close, but I have Near Vanish set to 0, and this doesn't seem to fix this. Any help would be appreciated, thanks.
Not sure, but could be that the particle field is too small and thus are also the particle sizes. This could be a simple math precision issue - there is a limited precision to all computers and at some point values get rounded off or clipped. This is always a result based on what combination of settings you use for your camera and Particular itself. Try to make the particle field bigger and adapt the particle sizes to compensate.
