About Me


Transitioning from a coder to a 3D artist. Houdini was the best option for me after I explored a different number of 3D software applications. I love the procedural workflow in Houdini and how easily accessible the attributes of the geometry are available to the user. This makes it a lot easier to focus on creating a good render and less time wasted on trying to figure out how to access certain geometry points or edges.

Calculating Simulation slow down significantly if cache ram size increased too high July 30, 2019, 11:07 a.m.

I enable checkpoints for every 25 frames or so, because it has helped in recovery from crashes or just when my PC runs out of ram. The overhead speed from checkpoints isn't too bad, but the size of the checkpoint files is what kills me. I remember using checkpoints the first time and it filled my ssd before the render completed.

Calculating Simulation slow down significantly if cache ram size increased too high July 12, 2019, 10:27 a.m.

Hi, I apologize if this post ended up in the wrong place on the forum. I wasn't sure where to post it.

I am doing a large scene with a large environment with high poly count 150M voxels for the proxy volume is used for FLIP collision detection. I noticed that if I enabled 50G of ram in the cache for the dopnet, it slows down significantly after an hour into calculating the sim. I am saving checkpoints, so I restarted the sim with 20G set for the dopnet and it runs a lot faster.

I suspect that the dopnet is using all the RAM to calculate and then buffers it all for the viewport and my computer thus finally runs out of RAM and starts using paging.

Is this possible? Or is it something else?

I am doing a file cache “save to disk” as well so I thought that locks up the entire Houdini, but I have noticed after I interrupt the saving task, the viewport is indeed loaded up with the sim, because I have enough points in the sim to notice the disk loading into the viewport.
