Detailed Description

Base class for all RFM-generated nodes.

Attributes:
    desc (NodeDesc): The full node description.
    nodeId (MTypeId): The node's unique id.
    typeName (str): The future maya node type name.

Member Function Documentation

def rfm2.maya_node.MayaPxrNode.about_to_delete_cb (   mobj,   dgmod,   data  )

static

This is called by MNodeMessage.addNodeAboutToDeleteCallback(). This
is a workaround for the absence of MPxNode.setExistWithoutInConnections()
in the python v2 API. The goal is to severe outgoing connections from
this node before it is actually deleted by maya to make sure downstream
nodes are not deleted too.

Args:
- mobj (MObject): The node about to be deleted
- dgmod (MDGModifier): A modifier provided by maya to ensure proper undo/redo.
- data (None): Arbitrary user data. Un-used.

def rfm2.maya_node.MayaPxrNode.compute	(		self,
			plug,
			block
	)

We may use this later to send edits more reliably to the renderer.

def rfm2.maya_node.MayaPxrNode.creator ( )

static

This will be superseded by the dynamic class.

def rfm2.maya_node.MayaPxrNode.getFilesToArchive	(		self,
			shortName,
			unresolvedName,
			markCouldBeImageSequence
	)

Maya API method

Here is the call graph for this function:

def rfm2.maya_node.MayaPxrNode.initialize ( )

static

This will be superseded by the dynamic class.

def rfm2.maya_node.MayaPxrNode.postConstructor

)

Maya API method

Here is the call graph for this function:

def rfm2.maya_node.MayaPxrNode.ramp_changed_cb (   msg,   plg,   otherPlug,   data  )

static

We are now using Maya's compound attributes, so we need to make sure
it is properly configured to reflect our ramp implementation
limitations, i.e. spline interpolation method is the same for all knots
and knots are sorted.
To avoid triggering infinite recursive evaluations, we rely on
MDataHandle to set plug values.

Here is the call graph for this function:

def rfm2.maya_node.MayaPxrNode.shouldSave	(		self,
			plug
	)

This is called for each node plug before saving the scene file.
Make sure we always save arrays to maya scenes.
