New PhysX Video - Full Chain and Sprockets - rjanders0003 - 03-25-2024
G'Day Everybody
I wanted to know if tyFlow could handle a full dynamic animation of a to scale bicycle chain and two sprockets. There were quite a few mind twisters to get it all working solidly, One that I didn't think about, is it seems that when turning into PhysX, there is a slight stretch of the objects and I need to add a tension roller to tighten the chain. Its just a 1 minute video but it was fun to make.
There were some quirks and things I would do in another way if I was to do it again. I would consider scaling up, I would place the chain differently before placing it in a loop, I would have a center point on the pins of the chain to make positioning perfectly.
Enjoy

You're doing a great job mate on this, and other tests and tutorials.
Just curious for this particular chain scene, what is the timestep?
You managed to do it with frame, or you had to go lower?
Did you changed default other 3 PhysX parameters of steps?

Thanks Mate
I will double check - in the middle of a 10hr render
Pretty sure final settings were.
Timestep 1/4
PhysX Substeps 16
Rest in tyFlow Main settings are default
Chain and sprockets broken down Hull is Compound by Element
