Flag

The term "flag" in TouchDesigner refers either of two concepts:

• the indicator of states of an Operator (bypass, display, lock), or
• option of a tscript command.

Operator Flags

Operator flags are located around a node in a network pane and/or in a network's "table" view (press "t" in the network to toggle).

When you press "t" in a network pane, it shows nodes in a table format, where the complete set of flags is visible on the columns.

Flags are not parameters and therefore changing a flag does not in itself cause a node to cook. You cannot export to a flag.

All flags are displayed and set using the opset command.

Flag states are retrieved with the opflag() expression.

Flags on all Nodes

• Viewer Flag
• Viewer Active Flag
• Lock Flag
• Bypass Flag
• Cooking Flag
• Immune Flag
• Current flag - the node is the current node in a network
• Expose flag - the node can be hidden from view in a network

Flags on 3D Object components

• Render - if off, the object will not be seen in any render of the Render TOP or Render Pass TOP.
• Display - if off, the object will not be seen in any camera viewer.
• Pickable - if off, the object will not be selectable in 3D Geometry Viewers or the SOP Editor.

Flags on CHOPs

• Export - if off, nothing is exported from that CHOP

Flags on SOPs

• Compare - displays the SOP's input geometry as a green wireframe for comparisons.
• Template - displays the SOP as templated geometry in 3D viewers. The grey wireframe template is not selectable or editable.
