Hi facr73, Thank you for providing your feedback. We apologize for the inconvenience. Upon review, we have confirmed that this issue is related to a current limitation within the iClone 8 Motion architecture. We have escalated this concern to our development team. In the meantime, we kindly advise you to avoid importing this specific type of data to prevent incorrect animation results when Props execute motion. We appreciate your understanding. We wish you a pleasant day! Jasmine Reallusion
