Learn about storing a mesh as a sequence of BIF files.
- [Instructor] For faster render times…and better interactive performance…for a liquid mesh, export it to…a Bifrost mesh cache.…This is a sequence of mesh files…of the format BIF or Bif.…BIF mesh export won't create its own output folder.…The export directory needs to exist first.…If Maya is open, exit Maya,…and then go to your current project…and navigate to the cache folder…and in the Bifrost subfolder, create a new folder.…
Maya will assume that the name of the current scene…will be used as the output folder.…I'll create a new folder using the scene file name.…Right click, and choose New, Folder,…and give it the name 03_04_bif_cache.…And now we can relaunch Maya.…Back in Maya in the FX menu set,…we see the Cache menu.…
Inside there are some sub-menus.…If the Bif_Cache sub-menu does not appear,…go to the Plugin Manager and enable BIF_Mesh.io.…Okay, so we've got it here in our menus.…Select the mesh object, scroll down in the outliner,…and select BifrostLiquid1Mesh.…And by the way, we could export any mesh object…
