Readonly markAllDefinesAsDirtySearch playground for markAllDefinesAsDirty

markAllDefinesAsDirty: (() => void)

Type declaration

    • (): void

    • Helper function to mark defines as being dirty.

      Returns void

nameSearch playground for name

name: string

Defines the name of the plugin

prioritySearch playground for priority

priority: number

Defines the priority of the plugin. Lower numbers run first.

registerForExtraEventsSearch playground for registerForExtraEvents

registerForExtraEvents: boolean

Indicates that this plugin should be notified for the extra events (HasRenderTargetTextures / FillRenderTargetTextures / HardBindForSubMesh)

useEnergyConservationSearch playground for useEnergyConservation

useEnergyConservation: boolean

Defines if the material uses energy conservation.

useSmithVisibilityHeightCorrelatedSearch playground for useSmithVisibilityHeightCorrelated

useSmithVisibilityHeightCorrelated: boolean

LEGACY Mode set to false Defines if the material uses height smith correlated visibility term. If you intent to not use our default BRDF, you need to load a separate BRDF Texture for the PBR You can either load https://assets.babylonjs.com/environments/uncorrelatedBRDF.png or https://assets.babylonjs.com/environments/uncorrelatedBRDF.dds to have more precision Not relying on height correlated will also disable energy conservation.

useSpecularGlossinessInputEnergyConservationSearch playground for useSpecularGlossinessInputEnergyConservation

useSpecularGlossinessInputEnergyConservation: boolean

Defines if the material uses energy conservation, when the specular workflow is active. If activated, the albedo color is multiplied with (1. - maxChannel(specular color)). If deactivated, a material is only physically plausible, when (albedo color + specular color) < 1. In the deactivated case, the material author has to ensure energy conservation, for a physically plausible rendering.

useSphericalHarmonicsSearch playground for useSphericalHarmonics

useSphericalHarmonics: boolean

LEGACY Mode set to false Defines if the material uses spherical harmonics vs spherical polynomials for the diffuse part of the IBL. The harmonics despite a tiny bigger cost has been proven to provide closer results to the ground truth.

Static DEFAULT_USE_ENERGY_CONSERVATIONSearch playground for DEFAULT_USE_ENERGY_CONSERVATION

DEFAULT_USE_ENERGY_CONSERVATION: boolean

Default value used for the energy conservation. This should only be changed to adapt to the type of texture in scene.environmentBRDFTexture.

Static DEFAULT_USE_SMITH_VISIBILITY_HEIGHT_CORRELATEDSearch playground for DEFAULT_USE_SMITH_VISIBILITY_HEIGHT_CORRELATED

DEFAULT_USE_SMITH_VISIBILITY_HEIGHT_CORRELATED: boolean

Default value used for the Smith Visibility Height Correlated mode. This should only be changed to adapt to the type of texture in scene.environmentBRDFTexture.

Static DEFAULT_USE_SPECULAR_GLOSSINESS_INPUT_ENERGY_CONSERVATIONSearch playground for DEFAULT_USE_SPECULAR_GLOSSINESS_INPUT_ENERGY_CONSERVATION

DEFAULT_USE_SPECULAR_GLOSSINESS_INPUT_ENERGY_CONSERVATION: boolean

Default value used for activating energy conservation for the specular workflow. If activated, the albedo color is multiplied with (1. - maxChannel(specular color)). If deactivated, a material is only physically plausible, when (albedo color + specular color) < 1.

Static DEFAULT_USE_SPHERICAL_HARMONICSSearch playground for DEFAULT_USE_SPHERICAL_HARMONICS

DEFAULT_USE_SPHERICAL_HARMONICS: boolean

Default value used for the IBL diffuse part. This can help switching back to the polynomials mode globally which is a tiny bit less GPU intensive at the drawback of a lower quality.
