Defines a node's cached data when participant EM Cached Playback Can be used to query or modify the attributes being cached

Warning: Do not store pointer or reference to this object; Users cannot construct or destroy this Maya object

Member Function Documentation

const MCacheSchemaAttributesRange& attributes ( ) const

inline

The attributes that are expected to be cached.

Warning: This list may differ from what Maya will cache in the frame-evaluation-time. Attributes skipped at frame-pre-evaluation time with `MEvaluationNode::skipEvaluation` will not be cached.

void reset ( )

Deprecated in 2022.0

Reset this schema to the minimal.

Warning: Resetting the cache schema from a parent class may cause Maya to crash

If the schema is being configured for Evaluation Cache, attributes() will only contain attributes required by downstream nodes or viewport
If the schema is being configured for Viewport Cache (hardware or software), attributes() will be empty

MStatus add ( const MObject & attribute )

Force the attribute to be cached.

This method allows you to cache input attributes or other animated attributes that are not fully understood by EM.

Parameters
