Short description of error
Setting cache path locks frame range to the cache available at a time of setting filepath to the the cache folder and does not update later.

Exact steps for others to reproduce the error

I have set a filepath of the cache to an empty folder, saved a scene and processing caches in the background via a script.
Working on lookdev of these caches is inconvenient as scene does not get any updated as caches get created.

Solution does not require directory observer but it wold be nice if blender at least tries to load a cache from disk during timeline scrubbing
even from outside of the frame range locked to limited frame range.
So far only way to update frame range of the caches is by either changing settings in cache panel (clicking checkbox on and off)
or updating filepath to the same exact path, literally by causing invalidation of the panel.

Please do not lock frame range of the caches or make this behavior optional. Please, try to load caches from outside
of the range even if frame range is locked. In case cache frames are missing from disk, please ignore.
Thank you.

Hi Sebastian,

What is the problem, you cannot reproduce it or something ? Or is it you think it is ok to leave blender
behave badly and just close the ticket without single a word of explanation ?

Fix is very simple, just do not delete the caches in the first place and UI controls can be kept unlocked. Also they may be split into two categories "loading" and "saving" rather then trying to do voodoo and automagically handle two mutually exclusive states.

Is this panel written in python ? I can rewrite it for myself unless the problem is really deep inside the system..

If I understand you correctly, you are requesting new functionality with the caching system.

For new functionality we want users to write up a proposal on how they think the new functionality should work and iterate on the idea a bit with other users (on rightclickselect).
Then when the idea has matured and has a very solid vision, we can look at it and perhaps try to integrate it. Or perhaps someone else sees your idea and decides to write a patch for it.

Hi Sebastian,

Thank you so much. I am new to blender and trying to find my way around it. Proposal sound great to me. Aren't you planning on replacing simulation of fluids with Manta flow, I think it has different caching system. Avoiding writing a proposal for a system which replacement is already half way through or in progress sounds like a better plan. Do you have manta flow integration proposal I could read ?
