hi again, maybe its easier to answer when i upload the files. archive is here this includes the rendered image sequence from maya, the maya scene and an ae-project with all imported and arranged. a particular-emitter is attached to a light that follows the null (and rendered sphere). does anybody now know what to do? by the way: my goal is to animate a vehicle in maya, composite it into real-footage and add some particles with particular, cause i dont like the particle-system from maya. thx, payton
