Hi Yuri, thanks for replying.
It is a bioreactor model which was shared to us by our client. It had some missing parts in it so we created those parts in 3DS Max and added them to the bioreactor and worked on the animation for it in 3DS Max itself. As I said I am not a technical person so I am attaching the latest model file for you to have a look. Let me know if you need anything else.
Thanks.
