A way to change how long Compiled Shaders are stored Please

Hey,

Is there a way to change how long we keep Compiled Shaders to unlimited?
I’m working on a project that has about 35 different maps and it’s taking me long to complete each individual maps,
as a result, sometimes if i din’t loaded one of my maps for let’s say 2 weeks i think, the compiled shaders are deleted somehow,
i don’t want that, because many maps are realy large and takes a lot of time to compile everything.

So is there a way to fix this so i can keep what was already compiled before?
Is there also a way to store the shaders to an other drive?

Thx.

I don’t think there’s any lifetime for compiled shaders. What would be the reason?

The only way for that to happen is for you to have invalidated the shaders yourself somehow and they just now come around to getting loaded and compiled. Either a shared material or a shared material function has been changed in-between loading the map. Of course it’s possible that you also manually somehow deleted the DerivedDataCache folder.
