That is very interesting and thanks for your reply, i’m using AE CS5 and CC Particle world, I know there have been changes to the plug-in and I looked them up when needed from your answer. If I turn floor to transparent or none, the particle in essence will continue falling if the particle comp has been embedded in another comp? I am running into difficulty when the camera is moving up and I want the particle to not be cut off from the particle comp. Is there anyway for this to be done? What does floor turned to none do? What it suggests…..
