Occlusion

Occlusion properties, you can set an occlusion map. This is the default occlusion attribute. The occlusion map use geometry occlusion information baked into a texture to modulate the ambient and direct lighting. The screenshots below demonstrate the use of occlusion maps and cavity maps:

Transparency

Transparency properties, you can specify values that change the transparency of the material. You can coose Blend, Additive, or Cutoff.

Additive

The additive transparency takes into account the diffuse and diffuse/emissive alpha.

• Alpha property is less than 0.5, only the specular highlights are visible. The material itself is completely invisible. We only see the specular highlight in additive modeTransparency is fully additive. Specular highlights at maximum
• Alpha <= 1.0, the material is semi-opaque with the diffuse/emissive component. If the diffuse component has an alpha, it’s transparent. Specular highlights, diffuse with alpha and semi-opaque diffuseSpecular highlights, diffuse with alpha and opaque diffuse

  Cuttoff

  Alpha slider. The following screenshots show the influence of the cutoff Alpha value.

  Clear coat

  Clear-coat shading uses physically-based rendering to simulate vehicle paint. clear-coat shading.
