Noise Mix

The Noise Blend operator, also found in the Node menu and RMB context menu, allows you to instantly mix together any number of nodes with a noise pattern. The only option, Mix Outputs By, determines which outputs of the selected nodes get mixed together.

Order will blend all sockets together based on their socket number on the node. If one node has more sockets than the other, empty inputs will be created for those channels.

Name will mix outputs together based on their name and create a blank input if a node doesn't have an output of that name.

Only Common Names will mix only the outputs that all selected nodes have in common, such as Color or Fac. Nothing will happen and a warning will appear if the nodes have no outputs in common.

Only First will simply mix the first outputs of each node.
