Bump MapNormal Map



Bump Mapping

Bump maps are controlled by a height map texture which is used to perturb the surface normal. Since only normals are perturbed, not geometry, it does not affect shadows. Bump maps do not contain directional information.

Height Scale: 0.11.03.0


Affected By Object Scale

This option forces the resultant bump vector output to scale along with the objects scale. Disabling this option will essentially remove any scaling bias, yielding more predictable results when blending bump maps and normal maps.

Flip Normal Y

This allows you to flip the Y axis of the normal map. Redshift expects normal maps in the OpenGL format making this option useful if the normal map was generated using a flipped uv coordinate format like DirectX.
