Squricle Normal: A Procedural Normal Map Generator

by Squircle Art in Render Setups

Procedural Normal Map Generation In Blender !

Squircle Normal is a compositor node group designed to bring normal map generation right into blender without any third party apps! Convert your height and diffuse textures into tangent/global space normal maps!

Specification:

The node group takes an image representing a texture and returns:

  • Tangent Normals: A tangent space normal map.
  • Global Normals: A global space normal map.
  • Inverse Global Normals: A global space normal map with negative z component.

See It In Action:

Leverage the power of blender's compositor for fine control over your maps!

Extracting the finest details from your image!

Near realtime results, fast preview!

Changes in v1.3:

  • Added invers global normals output. Useful in computing dot products.
  • Organized node tree.

Changes in v1.2:

  • Slightly faster.
  • Corrected the normal computing equation.
  • Removed derivative map output.

Changes in v1.1:

  • Optimized node tree.

Changes since Beta Version:

  • A basic central finite difference operator is now used instead of sobel operator. This improves performance but introduced subtle noise in high frequency details.
  • More accurate computation of normals.
  • 3x faster.
  • Global space normals were added.
  • Accurate derivative map was introduced.
  • NonSeamless map generation operator was removed.
  • MultiSpectrum operator was removed.
