AcidZack Posted September 16, 2021 Share Posted September 16, 2021 Hey everyone! This is my first post here! I have a scene where I'm caching a vellum grains simulation to a disk cache. I'm having trouble understanding why it takes so long. When I cache the simulation to ram in the viewport each frame takes about 15 seconds, however when I drop a File Cache SOP and save it to my hard drive each frame seems to take about 3 minutes. Could someone explain why this may be? I have tried saving to another drive and it didn't help. Quote Link to comment Share on other sites More sharing options...
symek Posted September 19, 2021 Share Posted September 19, 2021 How big are those files? Is it HDD or SDD? Are you using implicite compression (with *.sc postfix?). Did you delete attributes which are not needed for rendering? Quote Link to comment Share on other sites More sharing options...
AcidZack Posted September 21, 2021 Author Share Posted September 21, 2021 Each file is only around 2mb. I am deleting all attributes except pscale and v before caching. the sim only has about 100k points, it's not even the final, I just wanted to save it to disk. The file format was bgeo.sc. I initially saved it to my HDD, I tried my SSD (which id rather not save caches to), but it did not save any noticeably faster anyway.
