You cannot replace nCache frames for any Nucleus objects that have more than one cache node.
When on, the current object’s 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 an nCache, 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.
When on, the range of frames from the Start replace frame to the End replace frame is replaced for the current object’s 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 an nCache, 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.
When creating an nCache, one sample of your object’s simulation is taken every frame and saved to your nCache by default.
Evaluate every # frame(s) specifies how often samples are taken during nCache creation. For example, a value of 2 caches the simulation of the current object at every other frame of the Cache time range.
Save every # evaluation(s) specifies which samples are saved during nCache 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 nCache.
For more information, see nCache creation.
When on, the cache frames you want to replace are replaced with new simulated data.
When on, the cache frames you want to replace are deleted from their nCache files on disk. The deletion is permanent, and cannot be undone by Edit > Undo or Ctrl+z.
When on, no interpolation occurs between your object’s current cache frames and the frames you want to replace.
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.
When on, your original nCache file is renamed as the name specified in the Rename Interpolated Frames field.
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.
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 range and End interpolation frame range are only available when Interpolation frames is on.
These drop-down menus let you specify a tangent type for the cache interpolation before (In tangent) and after (Out tangent) the nCache 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 nCache.
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.
