Enable alpha testing. See Material#alphaTest.
Enable alpha to coverage. See Material#alphaToCoverage.
If ambient spherical harmonics are used. Ambient SH replace prefiltered cubemap ambient on certain platforms (mostly Android) for performance reasons.
One of "ambientSH", "envAtlas", "constant".
The value of Material#blendType.
The value of StandardMaterial#cubeMapProjection.
The type of fog being applied in the shader. See Scene#fog for the list of possible values.
The value of StandardMaterial#fresnelModel.
The type of gamma correction being applied in the shader. See CameraComponent#gammaCorrection for the list of possible values.
Make vLinearDepth available in the shader.
The value of StandardMaterial#occludeDirect.
The value of StandardMaterial#occludeSpecular.
Defines if StandardMaterial#occludeSpecularIntensity constant should affect specular occlusion.
Enable opacity dithering. See StandardMaterial#opacityDither.
Enable specular fade. See StandardMaterial#opacityFadesSpecular.
Enable opacity shadow dithering. See StandardMaterial#opacityShadowDither.
One of REFLECTIONSRC_*** constants.
Custom shader chunks that will replace default ones.
Shader outputs the accumulated shadow value, used for shadow catcher materials.
Skybox intensity factor.
Apply SSAO during the lighting.
The type of tone mapping being applied in the shader. See CameraComponent#toneMapping for the list of possible values.
The value of StandardMaterial#twoSidedLighting.
If cube map rotation is enabled.
If hardware instancing compatible shader should be generated. Transform is read from per-instance VertexBuffer instead of shader's uniforms.
The value of StandardMaterial#useMetalness.
If morphing code should be generated to morph normals.
If morphing code should be generated to morph positions.
Object containing a map of user defined vertex attributes to attached shader semantics.
If refraction is used.
If the environment chunks sample the scene environment, published by the renderer as
scene_envAtlas and scene_skybox, instead of the textures owned by the material
(texture_envAtlas, texture_cubeMap).
If any specular or reflections are needed at all.
The lit shader options determines how the lit-shader gets generated. It specifies a set of parameters which triggers different fragment and vertex shader generation in the backend.
You do not create one. The engine fills a LitShaderOptions from the material and scene state each time a StandardMaterial needs a shader variant, and every distinct set of values produces a distinct compiled shader. Developers rarely need to touch it: the material properties such as
useFog,useLightinganduseSkyboxon StandardMaterial cover the usual cases, and the values here mirror them together with the scene state. It is exposed for the rare case of customizing shader generation through StandardMaterial#onUpdateShader.
