I have a camera exported from maya. A camera flies through a landsape. I exported the cam to AE and made a solid with particular. Now, I would like to have the particles generated over a large volume. What I did now is that I have them emited very fast then freeze the time with Physics. It works well exept that the motion blur is also freezed in a very extreme position due to the fast speed in witch the particles is positioned in space. I read something about linking particluar to the camera with expressions but have no idea how to do that. Any ideas?
