Other Nodes

The following other nodes are miscellaneous and do not fit neatly into the other categories of nodes.

mmMarkerScale Node

The mmMarkerScale is used to compute scale and translate values for a transform.

mmReprojection Node

The mmReprojection node computes the screen-space position of an input transformWorldMatrix attribute. A Maya camera node must be connected to the camera attributes. The camera is used for all camera/screen-space values. The node can be used to feed into a camera display pan, effectively centering the screen.
