PbrMaterial Op

PbrMaterial

PBR/Physical Based Rendering Material for realistic materials


Can be used with Ops.Gl.Pbr.PbrEnvironmentLight for image based lighting or with standard Lights found in the op library.

You can drive the settings for your Ambient Occlusion, Roughness and Metalness (AORM or ARM textures) with a single texture or manually adjust the global setting. You can also try compositing an AORM texture in an Image Compose with additive RGB color channels.

Diffuse Color

R (Number)

amount of red

G (Number)

amount of green

B (Number)

amount of blue

A (Number)

opacity of material. Use Alpha Mode to change how this value is used.

Shader Parameters

Roughness (Number)

roughness of the surface

Metalness (Number)

blend F0 between 0.04 and albedo by this value

Alpha Mode index (Number: integer) Opaque  Masked  Dithered  Blend

adjust exposure used for tonemapping

Advanced Shader Parameters

Emission Intensity (Number)
Disable geometric roughness (Number: boolean)

don't automatically introduce roughness calculated from screen-space geometry density

Use roughness from normal map (Number: boolean)

calculate screen-space roughness from normals on top of geometric roughness
