Cached Playback unsupported nodes

Some nodes in the Maya dependency graph (DG) disable the Cached Playback process. This section refers only to animated nodes that disable Playback Caching. If the nodes are not animated, Playback caching is not affected by them. For example, you can use non-animated XGen nodes with Cached Playback, so long as they are static. (Where "Not animated" means any node that is not a part of the Evaluation Graph.)

Playback caching is disabled, and enters Safe Mode if Maya detects any unsupported nodes in the scene. When Cached Playback is in Safe Mode, the Cached Playback status line and the Cached Playback icon turns yellow. (See Cached Playback status line states for more information.)

When in Safe Mode, the Cached Playback icon turns yellow

textureDeformer nodes are unsupported and disable Cached Playback.
hairSystem nodes are supported only if "hairSystem.simulationMethod" is off or static and the nucleus node is set to disabled, regardless of the Cache Dynamics option (in the Caching section of the Evaluation Toolkit).

There is a separate Dynamics status line (different from the Animation status line,) where you can load and refresh nParticle and nCloth dynamics in your scene along with animation (nHair is not yet supported). Activate Cached Playback dynamics support using the Cache Dynamics option in the Caching section of the Cached Playback Preferences.

You can override limitations for any other dynamics and force Cached Playback for dynamics nodes using the following environment variable: MAYA_CACHE_IGNORE_UNSAFE_<nodename>.

Use the variables in the following tables for each unsupported node.

Note: See Setting environment variables using Maya.env for information on using environment variables.

Note: For more technical detail on Cached Playback, see the Maya Cached Playback whitepaper.

Bifrost

Disabling Nodes/Attributes	Supported Value	Force enable cache with
bifrostContainer		`MAYA_CACHE_IGNORE_UNSAFE_BIFROST`

Cache file

Disabling Nodes/Attributes	Supported Value	Force enable cache with
cacheFile		`MAYA_CACHE_IGNORE_UNSAFE_CACHE_FILE`

MASH

Disabling Nodes/Attributes	Supported Value	Force enable cache with
MASH_Jiggle		`MAYA_CACHE_IGNORE_UNSAFE_MASH`
MASH_Trails.trailsMode (Conditional support: certain attribute values disable caching)	Join the Dots (2) Connect to Point (3) Connect to Nearest (4) Connect by Distance (5) Constraint Pairs (6)
MASH_Flight	FALSE
MASH_Spring	FALSE
MASH_Falloff.falloffEventType (Conditional support: certain attribute values disable caching)	FALSE
MASH_Time.enableVelocity (Conditional support: certain attribute values disable caching)	FALSE
MASH_Time.simulateTime (Conditional support: certain attribute values disable caching)	FALSE
MASH_Orient.orientMode (Conditional support: certain attribute values disable caching)	FALSE

Muscle

Disabling Nodes/Attributes	Supported Value	Force enable cache with
cMuscleSystem.enableJiggle (Conditional support: certain attribute values disable caching)	FALSE	`MAYA_CACHE_IGNORE_UNSAFE_MUSCLE`

Note: Using Paint Muscle Weights with Cached Playback can create unexpected behavior. To avoid this, disable Cached Playback while painting weights.
