Help  Passing Through Collider?

I have a long rope, in a stretched position, and two ends are attached statically to two separate objects, keeping it firm. And there are obstacles in between. When I move one attachment up and down, rope passes through the colliders in between. It doesn't ignore though, I can see that there's some "collision" happening but it easily breaks through. I've tried out many different options, checked the phasers etc. I'm posting all settings below.

Your relaxation factor for collisions and particle collisions is 0.1 (10%). This means only 10% of collision constraints will be enforced, which is close to having no collisions at all. Set your collision relaxation factor to 1 (100%) so that collisions can be fully applied. From the manual:

Quote:Values lower than 1 will only partially enforce constraints. For instance, with a relaxation factor of 0.25 constraints will only have a 25% of their normal effect.

Most other constraint parameters don't make much sense either. Using 10 iterations in parallel mode with 200% relaxation will yield extremely costly, very unstable constraints. From the manual:

Quote:High values can be used to help speed up convergence in any of the two modes (sequential or parallel), but keep in mind that simulation stability can degrade.

Use less iterations in sequential mode with 100% relaxation, optionally cranking it up to 120% or 150% if you need extra "oomph". Only go to 200% if you're absolutely sure of what the implications are.

Let me know if I can be of further help. cheers!
