This section details the Substance Shader plug-in, which renders Allegorithmic PBR (Physically Based Rendering) substances in Viz Engine.

The plug-in takes into account the position, color and enabled/disabled state of the first eight Lights in the Scene. It also supports materials with alpha properties.

Note: This plug-in is located in: Built Ins -> Shader -> Texture

Substance Properties

Note: The Substance properties panel parameters are different for each selected Substance.

The following options are available in the Basic Tab of the Substance Shader:

The substance settings depend on the settings the creator of the material has exposed:

  • Substance: Uses a PBR Substances item (.sbsar file). Drag to the drop zone.

  • Environment Map: Uses a latitude/longitude panorama environment map image. Drag to the drop zone.

  • Anisotropic Filtering: Sets the image quality. The default value is 4X.

  • Relief Amount: Sets the relief amount that the shader applies.

  • Tiling: Sets the tiling.

  • Emissive Intensity: Sets the intensity of the emissive properties (if the substance has any).

  • Ambient Intensity: Sets the ambient light taken into account by the shader.

  • sRGB Base Color: Converts the base color map to sRGB (default: on).

  • Texture Rotation: Sets the rotation of the texture on the geometry.

  • Texture Scaling X/Y: Sets the scaling of the texture on the geometry.

  • Texture Position X/Y: Sets the position of the texture on the geometry.
