Geometry Cache > Replace Cache Frame

Replaces the current object’s geometry cache frames specified in the Replace Geometry Cache Frames Options window. See Replace geometry caches. This lets you strategically replace individual cache frames in a geometry cache file. For example, you can improve an object’s cached deformations by remodeling parts of the object at specific frames and then replacing those frames in its geometry cache file.

Geometry Cache > Replace Cache Frame >

Opens the Replace Geometry Cache Frames Options window. This window lets you specify which geometry cache frames are to be replaced for the current object’s geometry cache.

Current Time field: This field displays the current playback time and frame number. This field is read-only.
Current Time: When on, the current object’s geometry cache frame is replaced, and backups of the original unchanged cache and description files are generated (named backup#_originalCacheName by default).

For example, if you want to replace frame 12 in a geometry cache, this option lets you create a cache for frame 12 only and then replaces frame 12 in the selected object’s current cache with the newly created cache frame. Current Time is on by default.
Start/End: When on, the range of frames from the Start Replace Frame to the End Replace Frame is replaced for the current object’s geometry cache and backups of the original unchanged cache and description files are generated (named backup#_originalCacheName by default).

For example, if you want to replace frames 10 to 20 in a geometry cache, this option lets you create a cache for frames 10 to 20 and then replaces that frame range in the selected object’s current cache with the newly created cache. Start/End is off by default.
Evaluate every frame(s) and Save every evaluation(s): 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.

For more information, see Geometry cache creation.
Delete backup files: When on, the cache frames you want to replace are deleted from their cache files on disk. The deletion is permanent, and cannot be undone by Edit > Undo or +z.
No Interpolation: When on, no interpolation occurs between your object’s current cache frames and the frames you want to replace.
Interpolate Frames: When on, the cache frames before and after the frames you want to replace are interpolated to create a smooth transition between your object’s current cache frames and the frames you want to replace.
Rename Interpolated Frames: When on, your original cache file is renamed as the name specified in the Rename Interpolated Frames field.
Start Replace Frame / End Replace Frame: These fields let you specify a start and end frame for the range of cache frames you want to replace. Start Replace Frame and End Replace Frame are only available when Start/End is on.
Start Interpolation Frame / End Interpolation Frame: These fields let you specify a start and end frame for the range of cache frames you want to interpolate. Typically, the interpolation range would start before the frames you want to replace and end after the frames you want to replace. Start Interpolation Frame and End Interpolation Frame are only available when Interpolate Frames or Rename Interpolated Frames is on.

In Tangent/Out Tangent

These drop-down menus let you specify a tangent type for the cache interpolation before (In Tangent) and after (Out Tangent) the geometry cache frames you want to replace. This is useful when you want to smooth the interpolation between an object’s replaced cache frames and the rest of its geometry cache.

Linear: Deformations are interpolated linearly from the first frame in the interpolation range to the last, creating a smooth but straight-line transition to/from the replaced frames.
Smooth: Deformations are spline interpolated from the first frame in the interpolation range to the last, creating a smooth, gradual transition to/from the replaced frames.
Step: Deformations are stepped interpolated from the first frame in the interpolation range to the last, creating a transition that jumps to/from the replaced frames.
