Hi All, I've been having a problem with Houdini loading in heavy Alembic or FBX Files.

It takes up a huge amount of RAM even though the Alembic/FBX is only 4GB. Working with the file is also incredibly slow.

I’ve loaded an Alembic file that is 3.5GB, but once it’s open it uses 40GB of RAM, and once it’s unpacked it uses 80GB RAM, this makes it almost impossible for me to render on my machine because it jumps up to 120GB at render time.

I’ve tried this file in a few different 3d software and I’m not running into the same issue at all. In Blender it uses 12GB and in 3ds Max it uses 6GB

Let me know if there is something I’m doing wrong, I’ve been trying to debug this for a while, but I can’t seem to solve it. I feel like this is a problem with how Houdini handles geometry, so I don't think it's going to be an easy fix.


Cheers.

hi,

i can work quickly only a time, and then, houdini become really slow.
add only a node not connected take 10 to 20 seconds.
