However, it seems that very certain frames would not play back in UE4 despite having checked to be working fine when importing that same alembic cache back into Maya. When you playback the simulation Nucleus reads the cache files each frame, instead of recomputing the simulation. The XML (eXtensible Markup Language) description file contains a list of important cache attributes that Maya uses to locate the data files for your geometry cached objects and other useful information like its cache’s time range. If the appended cache overlaps in time with the enabled cache, then it is automatically blended with the enabled cache. You can specify whether you want your nCache to include position, velocity, or a number of other attribute values. Mar 21, 2015 · Hi everybody!
