This node stores all the settings for a
single nDynamic cache (nCache) and fluid effects nCache. Changes
to this node’s attributes do not affect its associated cache file
on disk. See cacheFile.
In the dependency graph
and Attribute Editor, nCaches are
represented as nNodeName#Cache# nodes. For example,
windTunnelShape1Cache1, windTunnelShape1Cache2, and windTunnelShape1Cache3
are the names of the three nCache nodes that contain the cache settings
for an fluid effect named windTunnel. In the Trax
Editor, nCaches are represented as nCache clips. Changing
an nCache node’s settings also changes the settings of their corresponding
nCache clips.
Cache File
- Base Directory
-
Specifies
the directory in which the current nCache node’s original cache
file resides on disk. By default, the base directory is: \maya\projects\default\data.
- Cach Name
-
Specifies
the name of the current nCache node’s original cache file on disk.
- Enable
-
When on, the current
nCache node’s simulation is used by its fluid object on playback.
When off, the current nCache node’s simulation is not used by
its fluid object on playback.
- Start Frame
-
Specifies
the starting time of the current nCache node’s playback. You can
change this attribute to modify when your nCache node’s playback begins.
- Scale
-
Expands or contracts
the time range of the current node’s nCache. If you increase the
scale, the node’s nCache simulation plays back slower. Decreasing
the scale has the opposite effect.
- Hold
-
Specifies the number
of frames to hold the last frame of the current node’s nCache.
- Pre Cycle/Post
Cycle
-
Specifies the number
of cycles that come before (Pre Cycle)
and after (Post Cycle)
the current node’s nCache.
You can use cycles to
repeat the simulation contained in your nCaches.
- Source Start/Source End
-
Specifies the start frame
number and the end frame number for the range of frames from the original
cache on disk that are contained in the current node’s nCache. The Source
Start and Source End values will not
match the Original Start or Original
End values if the current node’s nCache has been trimmed.
- Original Start/Original End
-
Specifies the start frame
number and end frame number of the current node’s original nCache file
on disk.
- Reverse
-
When on, the current
node’s nCache plays in reverse, starting with cache’s last frame. Reverse is
off by default.
- Oscillate
-
When on, the current
node's nCache oscillates between reverse and forward playback every other
frame, creating a continuous playback loop. Oscillate is
off by default.
- Multi Thread
-
When on, the current
node’s nCache is setup for multithreading during playback. Multi
Thread is off by default.
- Queue Size (frames)
-
Indicates the number
of frames of the nCache Maya will try to preload and keep in memory
if multithreading is enabled, but is not setup to preload the entire
cache. Queue Size (frames) is 20 by
default.
- Display Load Progress
-
When on, the percentage
of the multi thread cache memory queue that is full is displayed. Display
Load Progress is on by default.
Cache Description
Displays a selection of the information
contained in the XML description file for the current
nCache node. For more information on the values contained in the
Cache Description, see
nCache XML description file.
