microdot Posted May 29, 2015 Share Posted May 29, 2015 Just wondering if anyone else exp this. Houdini runs great on my box with flipbooks, etc, but when I use ROP driver to save a bgeo or obj seq, it gobbles up all my disk space during the write. Its a decent res fluid mesh, and about 200 frames, so I think I get it why it wants to use that memory during the write, but is there a way for me to change the dir path for that mem usage, away from my 500 GB HD and maybe to the 1TB? It's driving me a lil crazy, so any advice is appreciated, thanks.

lukeiamyourfather Posted May 29, 2015 Share Posted May 29, 2015 It could a couple of things but it sounds like the DOP cache. By default a DOP will cache things to the disk. If it's a big simulation it can easily grow to dozens or even hundreds of gigabytes. This can be disabled on the top level DOP node. Quote Link to comment Share on other sites More sharing options...

Georgie Posted May 29, 2015 Share Posted May 29, 2015 Not sure what you're asking - are you talking about RAM or HDD space ? If it's the former - try restarting Houdini before you commit to your final resolution sim. Or render through the command line. When it comes to HDD space, there are a couple of things you can do to minimize the usage - use .bgeo.sc files ; don't write out fields that you will not be using (ex; importing temperature out of a simple smoke sim that you're intending to render as is); delete attributes that you don't need before writing to disk. And of course you can create a folder on your HDD to use for writing out data and point the ROP to it . Fields and particle sims tend to pump out a lot of data tho. 200 frames could easily go to 50 gigs for a relatively simple sim. And that's coming from me - just a home user. I can totally imagine the fancy stuff on Vimeo being into the 100's of gigabytes. Quote Link to comment Share on other sites More sharing options...
microdot Posted May 30, 2015 Author Share Posted May 30, 2015 Yeah, sorry I neglected to also mention a big note. ALL the memory comes back after I quit. The bgeo files are fine, and about 30GBs, but its during the output that the hard drive chokes up and ROM gets eaten. Quote Link to comment Share on other sites More sharing options...
