Summary

Nomenclature

Nodes

• Panner: The Panner node moves a UV coordinate or other Vector 2 position by speed according to a Time value.
• OneMinus: The OneMinus expression takes an input value “X” and outputs “One Minus X”. This operation is performed per channel.
  • Examples: OneMinus of 0.4 is 0.6; OneMinus of (0.2,0.5,1.0) is (0.8,0.5,0.0); OneMinus of (0.0,-0.4,1.6) is (1.0,1.4,-0.6).
• TextCoord: Base UV texture coordinates. R color represent X axis, G color represent Y axis.
