houdini fluid sim soaking up HD space magically

[anupamd]

So I've been doing a sim of some fluids to my D: drive. But my c: drive keeps getting bloated with gigs every time I do a sim. I'm assuming that there is some scratch disk thats being written to somewhere during sim time. Problem is all the space is I've not got enough space on my C:\ to do the sim. How do you re-point the "scratch disk" to a user specified drive?

Thanks,

I think you need to point the $HIP and $JOB variables to your D: drive. You can do this by clicking "Edit" then "Aliases and Variables". Change them under the "Variables" tab.

You can also define the caching location for each DOP network. Look up "explicit cache" in the docs.

There's also the HOUDINI_TEMP_DIR environment variable.
