OmniPBRBase

MDL Identifier: OmniPBRBase

Description: OmniPBRBase is basic version of OmniPBR the default Physically based material available in Omniverse USD Composer. It is intended to be used in building custom Material Graphs. This material can describe most opaque dielectric or non-dielectric material.

Display Name	Type	Parameter	Default	Description
Albedo Color	color	diffuse_reflection_color	color(0.2,0.2,0.2)	The albedo base color
Albedo Tint	color	diffuse_tint	color(1.0,1.0,1.0)	When enabled, this color value is multiplied over the final albedo color
Roughness	float	specular_reflection_roughness	0.0	Determines roughness of the specular reflections. Higher roughness values lead to a more “powdery” look
Metalness	float	metalness	0.0	If 1.0, reflection will be colored and independent of view direction. If 0.0, reflection will be white and direction dependent
Specular	float	specular_level	0.5	The specular reflectivity of the material
Enable Emission	bool	enable_emission	False	Toggles emission on and off
Emissive Color	color	emission_color	color(0.1,0.1,0.1)	The color of the emissive light
Emissive Intensity	float	emission_intensity	40.0	The level of brightness of the emissive color
Enable Opacity	float	enable_opacity	False	Determines roughness of the clear coat
Opacity Amount	float	geometry_opacity	1.0	Toggles opacity on and off
Opacity Threshold	float	geometry_opacity_threshold	1.0	Attach bump or normal maps here
Enable Clearcoat Layer	bool	enable_coat	False	Enables the clearcoat layer
Clearcoat Weight	float	coat_weight	1.0	The specular reflectivity of the clearcoat layer
Clearcoat Tint	color	coat_color	color(1.0,1.0,1.0)	Base color of the clearcoat layer
Clearcoat Transparency	float	coat_transparency	1.0	Weighted blend between base material and the clearcoat layer
Clearcoat Roughness	float	coat_roughness	0.0	Isotropic roughness of the clearcoat
Clearcoat IOR	uniform float	coat_ior	1.56	Index of refraction of the clearcoat layer
