Hey all,

Running a vellum cloth sim that takes about 15 hours to simulate (long frame range). Sorry can't share the hip.

I ran a test with the exact same shot with/without the RefFrame node as the only difference.
With the RefFrame node added 5 hours to the sim time! total 20 hours.

5 hours more seems a bit excessive to me.

I have a pretty decent system (64gig RAM, 2080ti RTX, AMD Threadripper 1900) so I'm wondering if there is some kind of recursive looping going on in that node. I've looked inside and I don't see anything that jumps out.

Has anyone else had 25% time increases in sim times with a Ref Node?

Any help will be appreciated. Thanks.
