The Introduction of PBR Related User Interface

The Physically Based Rendering (PBR) parameters can be found in different user interfaces. These settings can convert single and multiple materials or even all materials in the entire project into PBR materials.

Modify Panel

  1. Convert Shader: Click this button to convert the current material or all materials in the project into PBR or Classic shader.
  2. Shader Type: This drop-down list determine the currently select material is set to PBR or Classic shader.
  3. Base Color: This is the primary channel for the Albedo of the material. In addition to this channel, the albedo is composed of other settings, such as the Blend texture, and the Diffuse Color.
  4. Metallic and Roughness: Use these two channels to determine the PBR material of the object in order to reflect the light from the IBL environment.

Project Setting Panel

Open the Project Setting panel (Shortcut: Ctrl + Shift + P). You can determine if the 3D viewer is PBR or Classic mode. The PBR mode allows the PBR materials to be rendered in the 3D viewer while the classic mode does not.

  1. Color Space: If you want to view the PBR effect in the 3D viewer, then you must select the PBR item in this drop-down list. It will activate the ability for the 3D viewer to render the PBR effects of materials.
  2. PBR Environment Setup: When you activate the PBR mode of the 3D viewer, you can click this button to set the ambient color to black (best color for PBR) and convert all materials in the project to PBR materials.
    • Set Ambient Color: Activate this box in order to set the ambient color to complete black when the environment color is set to PBR mode.
    • Convert Shader to PBR: Invert the Specular texture maps and assign them to the Roughness channel of all materials in the project to convert the materials to PBR materials.
