Tool Bar

The tool bar allows to clear a graph (bin icon), frame all or selected, zoom at a 1:1: ratio, enable or disable search box and nodes library, and finally force a refresh from maya nodes.

Search Box


Search Nodes Box

The search nodes Box allow to highlight all nodes starting with the given string. It handles  the * wild card as start, and is NOT case sensitive.

Nodes Library

The Nodes library let you drag and drop Channel Operator nodes directly from the editor (see the Channel Operators Overview for nodes type)

Workspace Manipulations

Some shortcuts are available in the Channel Operator Editor:

  • 'F' will focus on the currently selected Channel Operator nodes. If none are selected, it will focus on all of them.
  • 'L' will automatically layout the selected Channel Operator nodes. 
  • 'Tab' will open the node creation dropdown
  • Holding the 'Alt' key + left mouse button will draw a cut path to cut nodes links
  • Holding the 'Alt' key + middle mouse button while moving the mouse will move in the interface
  • Holding the 'Alt' key + right mouse button will zoom in and out in the interface
  • Using the mouse scroll wheel will zoom in and out in the interface

Node manipulations

  • New nodes can be created by hitting the Tab key, and selecting the node type to create in the dropdown list that appears:


Available new node types

  • Once selected, a node is configured by changing its attributes in the Maya Attribute Editor. Each Channel Operator type has its own list of attributes, see each Channel Operator help page for available parameters

  • Nodes can be connected together by a left click-and-hold from the node's output to the nodes's input or a middle click and hold from attribute to attribute.
  • A connection between two nodes is deleted by selecting it and hitting the delete key or via the cut tool (alt + left mouse button)
  • Nodes can be grouped by selecting a whole graph (select + right click, group). They can be ungrouped by selecting the group and chosing 'ungroup'
  • graphs or parts of graphs can be copy pasted (select + right click, cut / right click, paste)
