I've done a granular simulation and have recorded the sim using .prt file format While the positions and velocities seemed to have been exported fine it looks like Orientations have not been.
Am I missing something or are orientations/rotations not currently supported for export? Anyway you can think of that its possible?
I think the biggest problem is that Lucid particles don't have orientations, they are single point entities. Perhaps orientation can be determines based on motion but then those particles standing still will have indeterminate orientations.
