.MCFP File Extension
File TypeMaya Fluid Cache Playback File
What is an MCFP file?
Playback cache file generated by Autodesk Maya, a 3D modeling program; stores fluid effects, such as liquids, smoke, fire, and clouds in a disk cache so they can be played back without needing to be rendered on-the-fly.
Maya also creates "initial fluid cache files," which are saved with an .MCFI extension.
