Merges your current object’s enabled geometry caches and disables the cache nodes that are merged. By default, this operation does not delete any of your geometry cache nodes. See Merge geometry caches and Merge geometry cache clips.
Geometry Cache > Merge Caches > 
Opens the Merge Geometry Cache Options window. This window lets you specify the name, type, and location-on-disk of the merged geometry cache you want to create.
Specifies the base name for the merged geometry cache you want to create.
Sets the Cache Name as a prefix. When on, the base names of your merged geometry caches are the current objects’ names plus the specified Cache Name as a prefix. For example, the merged cache file names for an object named Ball with the prefix ted are as follows: ted_Ball1, ted_Ball2, ted_Ball3 and so on.
Set one of the following options:
When on, one merged geometry cache file (if One File is on) or one merged geometry cache file per frame (if One File Per Frame is on) for each of the selected objects, for the specified Cache Time Range, is created.
When off, one merged geometry cache file (if One File is on) or one merged geometry cache file per frame (if One File Per Frame is on) for all the selected objects, for the specified Cache Time Range, is created.
This option is only available when multiple objects are selected.
When creating a geometry cache, one sample of your object’s deformations is taken every frame and saved to your cache by default.
Evaluate every frame(s) specifies how often samples are taken during geometry cache creation. For example, a value of 2 caches the deformations of the current object at every other frame of the Cache Time Range.
Save every evaluation(s) specifies which samples are saved during geometry cache creation. For example, a value of 2 specifies that only every other sample specified by the Evaluate every frame(s) option is saved to your geometry cache.
