<ShaderProgramDescriptionCtr>

Description

Information describing the shader program.

Attributes

Type	Attributes	Description
	VertexShaderIndex	The index number of the vertex shader in the file.
	GeometryShaderIndex	The index number of the geometry shader in the file.
	MaxBoneCount	The maximum number of bones that the vertex shader can accept as input.
	MaxVertexLightCount	The maximum number of vertex lights that the vertex shader can accept as input.
	VertexLightEndUniform	The end position of the uniform register used by vertex light.
	IsSupportingRigidSkinning	Flag indicating whether the shader supports rigid skinning.
	IsSupportingSmoothSkinning	Flag indicating whether the shader supports smooth skinning.
	IsSupportingHemiSphereLighting	Flag indicating whether the shader supports hemispherical lighting.
	IsSupportingVertexMorphShader	Flag indicating whether the shader supports vertex morphing.
	GeometryShaderMode	The enumerated type representing the operational modes of the geometry shader. The standard runtime library does not support any specification except `None`.

GeometryShaderMode enumerators

Type	Attributes	Description
	None	Geometry shader not being used. This is the normal case for rendering.
	Points	A point geometry shader.
	Lines	A line geometry shader.
	LineStrip	A LineStrip geometry shader.
	PointSprites	A PointSprite geometry shader.
	SilhouetteTriangles	A Triangle List with Silhouette geometry shader.
	SilhouetteStrip	A Triangle Strip with Silhouette geometry shader.
	Subdivision	A Subdivision geometry shader.
	SubdivisionLoop	A Subdivision Loop geometry shader.

<Symbols> element

Bundles together multiple shader symbols. Child elements hold a multitude of these elements:
BoolShaderSymbolCtr, Vector1ShaderSymbolCtr, Vector2ShaderSymbolCtr, Vector3ShaderSymbolCtr, Vector4ShaderSymbolCtr,

Shader symbol attributes

Type	Attributes	Description
	Name	The name of the shader.
	IsEnabled	This sets whether to use `DefaultValue` or user-defined values (the material's shader parameters). If set to `true`, the default values defined by the child elements are applied. If set to `false`, the material's shader parameters (`<ShaderParameters>`) are used.

Shader symbol default values

The default values for shader symbols are defined as the child elements boolean Vector1Xml Vector2Xml Vector3Xml Vector4Xml.
These are used when the IsEnabled attribute is true or when there is no relevant uniform name for a given shader parameter.

<AttributeSymbols> element

Child elements hold the type information for numerous shaders (<AttributeSymbolCtr>).

`<AttributeSymbolCtr>` element attributes

Type	Attributes	Description
	Usage	`VertexAttributeCtrUsage` enumerator indicating how the attribute value is being used.
	Name	The name of the attribute value. The first character must be a lowercase "a," which indicates that this is an attribute.

VertexAttributeCtrUsage Enumerated Type

Value	Description
Position	Vertex position information.
Normal	Normal vector information of vertex.
Tangent	Tangent vector information of vertex.
Color	Vertex color information.
TextureCoordinate0	Texture coordinate 0 information of vertex.
TextureCoordinate1	Texture coordinate 1 information of vertex.
TextureCoordinate2	Texture coordinate 2 information of vertex.
BoneIndex	Bone index number information of vertex.
BoneWeight	Vertex bone weight information.
UserAttribute0	User attribute 0 information of vertex.
UserAttribute1	User attribute 1 information of vertex.
UserAttribute2	User attribute 2 information of vertex.
UserAttribute3	User attribute 3 information of vertex.
UserAttribute4	User attribute 4 information of vertex.
UserAttribute5	User attribute 5 information of vertex.
UserAttribute6	User attribute 6 information of vertex.
UserAttribute7	User attribute 7 information of vertex.
UserAttribute8	User attribute 8 information of vertex.
UserAttribute9	User attribute 9 information of vertex.
UserAttribute10	User attribute 10 information of vertex.
UserAttribute11	User attribute 11 information of vertex.
Interleave	Interleave format information.
