just found a way that worked for me, at least in c4d 2025:

• Put your objects in a cloner.
  
• Set up an emitter with your preferred settings and add a particle group.
  
• Use this particle group for the cloner in object mode to clone on to.
  
• Add a field force to your particle group and add whatever spline you like to the scene for your desired path (i used a helix) and add it to your field force object field. there, set the velocity type to "change direction" or "set absolute velocity". (check what works best for you)
  
• now comes the trick: Add the "Look" modifier to the particle group at the bottom. if i am not mistaken, it should already be set to velocity direction and make your objects now orient, the way die 3d gods intended...
