Description

Normal utility node that rotates all vectors of an input Normalmap in Tangent space. Doesn’t actually transform pixels, instead it modifies the values they represent. It can make use of an optional map to add random rotations to grayscale facets.

Inputs

• Normal: Color Input
  Base map to perform rotation on. Required.
• Rotation Map (optional): Grayscale Input
  Grayscale map that modulates Rotation strength.

Parameters

• Rotation Angle: 0.0 - 1.0
  Sets Angle by which to rotate the Normalmap
• Normal Format: DirectX, OpenGL
  Switch between different Normal Map formats (inverts the green channel)
