I’m having the same problem and am now in a real jam. Even the tracer tutorials on CC site exhibit the same problem they are just a bit hidden by the size of the clones. It’s very frustrating when things in C4D don’t work the way they are supposed to. This issue almost makes the tracer entirely useless for animation which is particularly insane since it’s part of the mograph module. Anyone have any ideas on how to force c4d to update the tracer? Xpresso maybe?
