Normals

Normal maps encode surface detail by modifying how light interacts with a material’s surface. These maps store direction data as RGB values, allowing complex surface details like bumps, scratches, and indentations to be rendered without additional geometry. Surface normals affect all lighting calculations including reflection, specular highlights, and shadow termination.

OmniPBR Normal Map Flip U Tangent

Flips the U Tangent vector.

OmniPBR Normal Map Flip V Tangent

Flips the V Tangent vector. By Default, OmniPBR is setup for DirectX normal maps. Set Normal Map Flip V = false for OpenGL.
