Description

Shader scripts used for all rendering.

Most of the advanced rendering is controlled via Material class. Shader class is mostly used just to check whether a shader can run on the user's hardware (isSupported property), setting up global shader properties and keywords, and finding shaders by name (Find method).

See Also: Material class, Materials, ShaderLab documentation.

Static Properties

enabledGlobalKeywordsAn array containing the global shader keywords that are currently enabled.
globalKeywordsAn array containing the global shader keywords that currently exist. This includes enabled and disabled global shader keywords.
globalMaximumLODShader LOD level for all shaders.
globalRenderPipelineRender pipeline currently in use.
maximumChunksOverrideSets the limit on the number of shader variant chunks Unity loads and keeps in memory.

Properties

isSupportedCan this shader run on the end-users graphics card? (Read Only)
keywordSpaceThe local keyword space of this shader.
maximumLODShader LOD level for this shader.
passCountReturns the number of shader passes on the active SubShader.
renderQueueRender queue of this shader. (Read Only)
subshaderCountReturns the number of SubShaders in this shader.

Public Methods

FindPassTagValueSearches for the tag specified by tagName on the shader's active SubShader and returns the value of the tag.
FindPropertyIndexFinds the index of a shader property by its name.
FindSubshaderTagValueSearches for the tag specified by tagName on the SubShader specified by subshaderIndex and returns the value of the tag.
FindTextureStackFind the name of a texture stack a texture belongs too.
GetDependencyReturns the dependency shader.
GetPassCountInSubshaderReturns the number of passes in the given SubShader.
GetPropertyAttributesReturns an array of strings containing attributes of the shader property at the specified index.

GetPropertyNameIdReturns the nameId of the shader property at the specified index.
GetPropertyRangeLimitsReturns the min and max limits for a Range property at the specified index.
GetPropertyTextureDefaultNameReturns the default Texture name of a Texture shader property at the specified index.
GetPropertyTextureDimensionReturns the TextureDimension of a Texture shader property at the specified index.
GetPropertyTypeReturns the ShaderPropertyType of the property at the specified index.
