Hi All,

As a new user I am working my way through the tool shelf and I have come to cloth. I am a bit shocked at how slow Houdini cloth calculates.

Why does Houdini only use 1-CPU to calculate the cloth sim? How do I turn on multiple CPU calculation for cloth in Houdini? If not that, any tips on speeding up cloth calculations?

Blender and C4D seem to be 10x faster for the basic plane draped over a sphere test.

Hello.
Yes cloth sim very slow in Houdini and I use Maya to create cloth sim.
Seems Houdini 14 have good solution for that and I think best way is:
wait until h14 release.
Interaction with another solvers also need a lot of work in h!!!
Hope in new Houdini we have speed and interactions.

As a side note: for anyone interested in going beyond simply using the cloth, and related FEM in Houdini, check out:

Thanks for the replies, I also found this related thread as well.
