Efficient way to reduce cache size

[ttdww]

Something that's helped speed up workflow is to be able to command-line convert to lower detail (larger voxel spacing) copies of the cache. Then I can script-replace all the caches, do test renders, scrub fairly quickly in timeline, move sims around, etc. Then set back to the high details cache versions for a final render. There's another command-line tool that allows skipping of voxels :cough: not naming names ;D. I didn't see that option in the .aur converter tool, so am wondering how this could be done without having to pipe the sim into a new sim box and rerun at lower detail. When you have 30 sims in a scene, that would take a lot of time. Thoughts? or perhaps something I've overlooked. Thanks!

Sure, this can be added fairly easily and I've thought about it for a few years now, let me see if I can squeeze this into the schedule cause I've been sidetracking way too much over the past year and the core of the software has been neglected

Fantastic! Thank you!

Hey, in the latest nightlies (https://nightlies.chaos.com/#/phoeni...ghtly/20220311 and https://nightlies.chaos.com/#/phoeni...ghtly/20220311), the cache converter can increase or decrease the grid resolution of caches:

cache_converter.exe -srcfile "PhoenixFDLiquid001_####.aur" -dstfile "PhoenixFDLiquid001_res_####.aur" -gridresscale=2.3

The new option -gridresscale will decrease the resolution if you use a value below 1.0, and will increase it when using a value above 1.0.

Note that increasing the resolution will simply scale the grid but will not add any extra detail.

Cheers!
