Wiresolver - stick/stop on collision Dec. 5, 2017, 12:48 p.m.

Set the wiresolver2 Tolerance to 0.5.
Thanks - this helps to cheat a bit but the force is still influencing the wires, they still wiggle a bit.

I will try to build what derrick suggested but this is new ground for me so time will tell.

As far as I understand the Wiresolver is a bit different and doesn't have a built in simple “disable sim” attribute for the points of the wire.

Thank you very much for the tips.

Crowd and Volume collisions Dec. 5, 2017, 8:11 a.m.

For small crowd I guess it's ok, but I always think about some more extreme cases For example I have a scene with 5000 agents - the VDB generation (which is what the Collision Source does)kills my computer
Thanks for sharing what you did, though.

Crowd sim - missing parts in render - random and changing between frames. Dec. 4, 2017, 4:31 p.m.

I've tried it before you posted but didn't succeed. However, now I did it again setting both current layer and collison layer to “default” (I don't need the collision layer anymore, because the sim is done) and on one of the frames it works. I'll set up an overnight render to see how it goes.

Thank you for your swift reply. If there are any other ways, maybe more “proper” ones, I would love to learn about them.

EDIT: It helped a lot but there are some frames that still have clipping geo. I couldn't continue - no more time. I'll try to get back to the project in the future. That's often a problem for me with Houdini - some small things that stop me from using it in fast paced production - usually those things are not mentioned in official videos or the manual (this clipping problem should be stressed somewhere).
Here's another possible solution: []
