Regarding the necessity of using tyflow for this - there are lots of benefits of having this simulated instead of using pathdeform (which I did, previously). Things like not having to hand animate secondary motion (beyond flex) and matching teeth to the belt so that no penetrations occur as well as moving the belt in place or having it snap or folding dozens in a shipping crate, etc...
I'm currently looking at producing tons of animations with this for all kinds of belts and use cases so tyflow is a godsent in that regard!
Thanks for your explanations regarding the Physx solver... I actually did play around with very high movement (and other) spring values (as suggested by the documentation) but for whatever reason I never tried increasing the damping values accordingly. that helped a lot.. Apparently in trying to find a solution I actually made things worse with other bind settings I messed around with - so your clean file helped a lot!
I did some stress testing and found this to work pretty well now: https://imgur.com/a/SSBvyOm (settled on 10.000.000 for movement and 50.000.000 for swing settings, using 100k and 1mil in damping settings respectively)
Also as a side note: I was fighting against gravity previously (belt should be straight, not hanging but still conform to the shape of the gear (which is an issue with spring settings too high) - to counter that I previously decreased gravity but now I figured that increasing the frame step resolution to 1/4 makes a huge difference in keeping the springs stiff even at realistic gravity values
cheers!
