Help Ropes Jitter in Crane Movement

I forgot to enable the sharing in Google Drive. Now I have enabled it so you can check it as well if you can notice any specific pattern in jitter.

Thanks a lot for pointing out the probable causes, i'll look into them one by one as well to see if any one of them is causing the trouble or not

The video looks as if the solver is parented to the crane's boom, and the boom is being rotated in Update. So Id' look for causes #1 or #2 in the above list, I think the third one can be safely ruled out. #1 is the most probable one, specially since you mention that adding more ropes causes jittering to be worse, which makes sense since more workload increases the frequency gap between Update and FixedUpdate().

Also note that parenting the "load" (the gray box hanging from the ropes) to the crane as it seems to be the case in the video doesn't make much sense: that will kinematically move the load together with the boom which is certainly not what you want in any crane. It also doesn't make sense for the solver to be part of the boom: that will simulate in the local space of the boom, while you most certainly want to simulate either in world space or the crane's local space.

kind regards,
