Bifrost - lost cache files...

[plata.jozef]

Hi, 

My scene is 120 frames long. When I was pretty happy with my bifrost sim I decided to bump up values for greater resault (grid set to 0.05).

After about 6 hours I decided to stop sim. It was calculating 110frame, that was enough for me. I had to wait about 30 minutes for STOP to make bifrost stop (i guess it had to finish calculations of 110 frame).

How big suprised I was when I looked into my cache folder and found that all frames from 1 to 105 are missing!!! there was only 4 (!!!!!!!!!) frames in the folder.

I tried caching with low settings before and everything was ok, all frames were cached. So what happened with 105 frames of high-res sim?

I'm very confused

How did you cache? Via Bifrost > Compute and Cache to Disk? Or did you just play your sim?

Don't forget, there's a difference between 'scratch' cache and 'user' cache. It sounds like you were simply writing to scratch cache, which is stored in memory (up to a certain amount, then it overflows to disk).

As for taking so long to stop evaluation, that's a known issue, where you can't break mid-process. We're figuring out how to fix that.

How long were your frames taking to sim anyway?

Hi agraham,

Thank you for your interest in the problem. I will look into the files when I will have a bit more time. But I'm pretty sure the cache was made by bifrost > computa and cache to disk.

I'll try to recreate this and let you know.
