Learn about load simulation from a disk, and disabling and re-writing a cache.
- [Narrator] In this movie we'll look at reading,…disabling, and rewriting a Bifrost user cache.…Before saving a scene that references a cache,…it's a good idea to rewind to the beginning of the timeline…before the simulation start frame.…That way Mya will not need to access the cache…when the file first loads.…We can control when that access happens.…In this case we can press the play button.…The cache gets loaded in when the timeline…reaches the first frame of the simulation.…
It may take a moment to load the entire cache…because in this case it's 15 gigabytes.…But once it's loaded, the cached frame range…appears in blue when we select the Bifrost liquid solver…or our liquid properties node.…I'll select one of those,…and the cached frame range is displayed in blue.…We can press stop.…At this point we could build…a play blast if we wanted to.…We also need to talk about…how to make changes to the simulation.…Maybe we make a play blast and we don't like what we see.…
To make changes we need to disable the cache.…
