Hello!

It's been a while that I've been looking on tutorials or forums how to launch a simulation via HQueue.

I managed to make a render farm with my computer and my nose I can render images. But I didn't understand how to run a cache simulation on the render farm. Could someone please explain me how to do it?

I don't understand how to share my slices between two machines, what are the node controls to use, and what are the clusters ?

Thank you

Please someone help ?

What are you simulating?

Hi, I need to simulate for exemple sand, fire and later water, in fact I want to know the workflow. To calculate my cache files with multiple computers

this example may not be the right one, but in the idea I would like to be able to do this kind of physics calculation on several machines.
I don't know if I'm clear, excuse me.

Okay, for that kind of sim, you can only run it on one machine. You do not need the distributed features that the hqueue simulation ROP includes…. those are for distributing fluid sims and such.

For a RBD or soft-body sim, you can simply plug a geo ROP into an hqueue render rop and ensure that “Batch all frames in one job” is toggled on. This will send the job to one machine and create the geo for you.

For simulating water and other such sims, there are a few docs explaining how to do this:

Thank you i will try
