The the object and the particles must move independantly of the camera ….. so parenting everything to the camera wouldn’t work..
The camera is just dollying in towards the scene and the object with the particles are dancing in front of it and then going off deep into z space..
My problem is that when I move the camera inward the particles appear to ride higher and higher in the scene. so the camera is just not seeing the particles the same way that it sees the object..
Everything works fine as long as I don’t move the camera.
