Lens Iris/Aperture blade closing and opening animation


Hi, I am new here :slight_smile: hopefully you guys can help me. So I am trying to animate the aperture blades for a inside lens opening/closing. Now for the past few hours I am messing around with rotation constraints and I am completely lost…

How do I animate aperture/iris blades closing and opening like that in a real lens. I found a tutorial for After Effects and Blender but nothing on the internet for 3Ds Max, how do I achieve this similar result in 3Ds Max 2020.




did it years ago, can’t guarantee it will work for 2020


Thank you so much vusta, that is exactly what I was looking for, highly appreciate it!
