Append to an existing Bifröst user cache

You can extend the frame range of a simulation, then append newly cached frames to its existing user-cache without having to recache the entire simulation. To append to an existing user cache, Bifröst needs to read at least one previously cached frame before it can accurately simulate the extended frame range. See Create a Bifröst user cache.

1. Select the container for the simulation that you want to cache.
2. Select Bifrost > Compute and Cache to Disk > .
3. Set Write Mode to Read/Write.
4. Make sure that other settings are as desired.
5. Click Create.

   Bifröst reads the existing cached frames, then computes and saves the extended frame range to the user cache.
