Shader Parameters

Common Parameters

SettingDescription
Quality

Controls the quality of the specular reflection in the viewport. Available settings :

  • Very low (4 samples per pixel)
  • Low (16 samples per pixel) - (Default)
  • Medium (32 samples per pixel)
  • High (64 samples per pixel)
  • Very High (128 sample per pixel)
  • Ultra (256 samples per pixel)
Horizon Fading

Fade specular reflections based on the horizon view angle. Requires a normal map in the Mesh map slots.

Emissive IntensityBrightness multiplier of the emissive channel. Useful to create very bright emissive colors to use with the Glare post-effect.
AO IntensityAmbient Occlusion intensity when multiplied over the lighting of the viewport.

Parralax Occlusion Mapping

SettingDescription
Enable

If checked, enable the effect.

Strength

Amount of the parallax effect to create.

Minimum Samples

Minimum amount of pixels to sample when applied the parallax effect. Raising the minimum value can be beneficial when looking at planar surfaces with a low angle. However in some other cases using lower values can help.

Maximum Samples

Maximum amount of pixels to sample when applied the parallax effect. Higher values will improve the look of the effect but will cost more performances.
