Having a problem creating a dust simulation for the background of a scene. I've created a basic rectangle emitter beside the screen which is 10,000cm^2 (have tried increasing and reducing this size but results are all the same). However these particles once emitted all seem to kill themselves once they reach a certain distance within the scene, and it is the same distance for all. There are no kill modifiers set, and its not the clipping distance of the camera/scene as it is the same distance in all 3 dimensions that it cuts off at. Is there an in built emitter range within X-Particles that kills them once they reach a certain border? And if so, is there any way around this? I do have quite a large scene, but i'd prefer to keep it to scale than having to reduce everything down.
Cheers
