Caches (writes out once and then reads from) geometry (possibly animated) to disk. This node combines the functionality of the Geometry render node and the File node to let you write out cache files and then read those files on disk instead of cooking its input.

The main aim of this node is to provide tools for creating synchronized SOP and a TOP graphs with each other, that can cache your entire Houdini scene with multiple file caches and wedging options at a click of a button.

Caches (writes out once and then reads from) USD layers (possibly animated) to disk. This node combines the functionality of the USD ROP and the Sublayer LOP to let you write out USD a file and then read that file on disk instead of cooking its input. Use a Cache LOP:lop/cache as an input to this node, to get more control over subframe sampling.

Oct 26, 2015 · In my houdini scene I have some file cache nodes which I want to execute from a hyton shell. I was able to start a alembic rop operator via: hou.hipFile.load("C:/data/myTestFile.hip") hou.node("/obj/geo1/rop_alembic1").render()

Dec 5, 2020 · I only did a 40 frames smoke simulation but at the last frame has taken so long, more than the others 39 frames, an only say Evaluating python, it has been caching for more than 4 hours, and in the task manager, Houdini is using 0.2% of the CPU.

Apr 5, 2022 · If you know Houdini Python you could create a python script that you can plug into the "Pre-Render Script" that would save a backup file somewhere just before it begins to cache. I've never done it myself but I imagine that's one of scenarios that such a feature was added for.

Apr 27, 2023 · I want to free some space and delete the cache files that are not used anymore. Is there an easy way to do that or do i have to manually go to each Filecache, look which version is used and then delete the other versions?

Nov 22, 2020 · Simple try to cache external JSON data loaded via Python in Houdini. The data can be used time based/animated with in my case 120fps :-)

A simple tool that allows easy acces to relevant data of a file cache or render on disk from within houdini. The tool uses simple python logic to access the files on disk and prints out a handy summary of this information.

Sep 21, 2022 · Is there an API for clearing the cache manager (https://www.sidefx.com/docs/houdini/ref/windows/caches.html) from python? As far as I know you can clear the cache of the SOP nodes using a hscript command in python SOPCACHE [www.sidefx.com].
