I basically need to animate about 5 or 6 cylinders that push a rubbery sealing material down the production line in a somewhat complex pattern so doing it by hand with keyframes is not an option. The cylinders are not in a straight line or only below the substance which complicates things.

My idea is to use physics and cloth with the correct constraints, settings and options to achieve this effect.

I require the cylinders to rotate constantly at the same speed troughout the animation giving off kinetic energy to the cloth, not affected by the cloth weight, pushing it forward. The cloth needs to be stiff and not buckle inward under the strain because that just wouldn't happen. It's a gasket sealing material and that wouldn't happen IRL. It's several mm thick and very

I need some help and helpful tips from people who're experienced in animation.

List of requirements:

Extremely rigid "cloth" that acts like rubber. I am fine working with extensions.

rotating cylinders that are not afected by physics in their rotation but do transmit energy via friction

Can you give me some helpful pointers? The tests i've been making have been somewhat abysmal and it's a pretty specific thing so there aren't many tutorials around.

    $\begingroup$ I think it my be good to narrow down the question to a specific problem, as it stands this is far too broad. As as many separate ones as you like. $\endgroup$ – Duarte Farrajota Ramos Jul 5 '17 at 19:09
  • $\begingroup$ Hmmm Well really what i need to know is how to make a rubber like substance, either using extensions or base blender with cloth and how to animate an object that rotates consistently at the same speed (not affected by physics IE a massive body) but that does give off translational energy with a high friction koeficient to the track of rubber. I guess i'll have to split it then. $\endgroup$ – Blaž Žnidaršič Jul 5 '17 at 19:30

  • $\begingroup$ It might also be helpful to add a few reference images of what you are trying to achieve, its a bit hard to follow this all from words alone. CLoth physics in Blender has a rubber preset for rubber like materials, though I don't think it supports very detailed stretching models. $\endgroup$ – Duarte Farrajota Ramos Jul 5 '17 at 22:18
  • $\begingroup$ Ah, i dont need any stretching. Its a sealing gasket material. Basically all i need is for it to bend on one axis while maintaining shape so i can string it along the rotating cylinders. I will try with the presets. Leather looks promising and see what i can make of it. If not i will create much more specific questions! Thanks. $\endgroup$ – Blaž Žnidaršič Jul 6 '17 at 7:16

I'm sorry, the question was way too broad.

I've gotten a partial solution from Duarte Farrajota Ramos by experimenting with presets and ramping up bending to 1000 and structural to 500 for the rubbery material.

I'll create a new question for how to propel the piece of ruber track in the animation forward.

constant rotation investigate drivers, and if clothes are not working for you (ea you cant make something more stiff then the program allows to, maybe try a softbody instead. (ea jelly pudding)
