Hi!

My Solver as a Start Frame at 1. When I run a simulation and scrub the timeline to frame 1, it erases the cache. Is there a setting to avoid that?

Did you try setting your timeline to start at frame 0 while keeping your solver's star at frame 1?

A.

the cache should not erase when you go to the start frame as long as it's still blue (not outdated) and as long as it fit all in the cache memory set for particular DOP node, since if not it would forget first frames already so needs to compute from beginning

if the cache is already orange (or with already erased first frames) and you just want to play it without reset, then you can disable simulations by clicking on the Brain icon
