    Hey everyone,

    Working on a project for a client and trying to figure out an approach to make a dynamic tape spew out of the cassette. I was thinking a spline on an emitter, but I don’t know if that will work since the spline has to be connected at the end. If anyone has an idea how to solve this that would be extremely helpful. I’ve attached a photo of an example of what I am trying to accomplish. Thank you.

    if you can get away with not seeing where the tape lands, you can just use an emitter rocking back and forth and then trace/connect the particles into a spline. If you have the see it land, that is a bit trickier, maybe fake it, draw out the full spline by hand then animate a sweep, then use effectors to give it some life? good luck!

    How about this? You can make the Birth spline longer and tweak the angular clamp to help or hinder twist. Currently this runs right out of the cassette. Still thinking about best way to stop it (fields maybe?). Right Capstan can be animated more or less to provide tape undulations. Tape width can me modified by the rectangle spline but you will also have to alter the Pearls’ z width as they are the only objects colliding – the swept tape is just along for the ride.

    I just realized I should have put what amounts to a pinch roller in there because the tape twists as it comes out. So just take that right capstan and duplicate it, make the new one a child of the right one and move the new one to the left, leaving a decent gap between for the tape to slide through. This will keep the tape from twisting until it has left the cassette.
