Hi all,

I am very new to Houdini and am using it for one of my school projects to learn the software. I am working on a pyro sim to composite into a live action shot and I started working on it however I cannot seem to figure out how to scale the simulation box. I looked in the pyro and pyrosolver nodes but cannot find it. Anyone know where it is?

Thanks

The pyro (Smoke Object) has a Size and Center parameter.

You can also resize it externally with an expression or from the Volume Fluids shelf (resize fluid).

It's also possible to resize automatically but it's a custom setup and sometimes fails so it is a little tricky at times; Try the Gas Resize Fluid.
