Bug / Crash Obi rod is not working properly

[icl92]

We want to simulate the following cable twisting effect using obi rod.

The Obi rod example already has the above effect, the only issue is, if we change any variable the simulation fails.

Is there any documentation explaining all the properties required for the obi rod , at-least a tutorial how to simulate the obi rod twisting example.


The final output which we are trying to achieve is to combine multiple cable and perform twisting on them.


Example : https://www.youtube.com/watch?v=vvG-lPYfzcY


We want to know, Can we use multiple Obi rod using same obi solver for combined cable twisting.

Is there any tutorial or post explaining how to simulate the the obi rod twisting effect using two wires, are any parameters to be taken care for the collision to work.


The Final Output will be as shown in the Below image






Kindly waiting for your reply.



josemendezHi,

Sorry but we're unable to reproduce this. It works just fine for us. Can you specify exactly what does not work?

Note that the sample scenes often tweak per-particle attributes to get the desired stiffness (particle masses and rotational masses, specifically). Creating a rod from scratch won't yield the same results as the ones in the sample scenes. To increase rod stiffness (resistance to bending), increase your particle's rotational mass.

Same goes for particle phases. Phases dictate which particle-particle and particle-collider contacts are pruned, and which ones progress to actual collisions. Make sure your rope particles are set up in different phases, or they will ignore collisions with each other. See:
