PrePassRenderer

Class PrePassRenderer

Renders a pre pass of the scene This means every mesh in the scene will be rendered to a render target texture And then this texture will be composited to the rendering canvas with post processes It is necessary for effects like subsurface scattering or deferred shading

The render target where the scene is directly rendered

disableGammaTransform: boolean = false

Set to true to disable gamma transform in PrePass. Can be useful in case you already proceed to gamma transform on a material level and your post processes don't need to be in linear color space.

doNotUseGeometryRendererFallback: boolean = true

Prevents the PrePassRenderer from using the GeometryBufferRenderer as a fallback

excludedMaterials: Material[] = []

Force material to be excluded from the prepass Can be useful when useGeometryBufferFallback is set to true and you don't want a material to show in the effect.

excludedSkinnedMesh: AbstractMesh[] = []

To save performance, we can excluded skinned meshes from the prepass

mrtCount: number = 0

Number of textures in the multi render target texture where the scene is directly rendered

renderTargets: PrePassRenderTarget[] = []

All the render targets generated by prepass

TextureFormats: { format: number; name: string; purpose: number; type: number }[] = ...

Describes the types and formats of the textures used by the pre-pass renderer

  • Adds an effect configuration to the prepass render target. If an effect has already been added, it won't add it twice and will return the configuration already present.

    Parameters

    • cfg: PrePassEffectConfiguration

      the effect configuration

    Returns PrePassEffectConfiguration

    the effect configuration now used by the prepass

  • Returns PrePassRenderTarget

    the prepass render target for the rendering pass. If we are currently rendering a render target, it returns the PrePassRenderTarget associated with that render target. Otherwise, it returns the scene default PrePassRenderTarget
