Class BasicShaderDataProvider

Namespace: ValveResourceFormat.IO
Assembly: ValveResourceFormat.dll

Provides hardcoded shader data mappings for common shaders as a fallback when shader files are unavailable.

public class BasicShaderDataProvider : IShaderDataProvider

Inheritance

object ← BasicShaderDataProvider

Implements

IShaderDataProvider

Fields

CommonTextureSuffixes

Common texture input names and their corresponding file suffixes.

public static readonly Dictionary<string, string> CommonTextureSuffixes

Field Value

Dictionary<string, string>

TextureMappings

Hardcoded texture channel mappings for known shader types.

public static readonly Dictionary<string, Dictionary<string, (ChannelMapping Channel, string Name)[]>> TextureMappings

Field Value

Dictionary<string, Dictionary<string, (ChannelMapping Channel, string Name)[]>>

Methods

ConvertTextureToInput(string)

Converts a shader texture parameter name to an input texture name.

public static string ConvertTextureToInput(string textureType)

Parameters

textureType string

The shader texture parameter name (e.g., "g_tColor").

Returns

string

The input texture name (e.g., "TextureColor").

GetBlendState(Material, IReadOnlyDictionary<string, long>?)

Gets the blend state of a material for the default dynamic combo.

public RsBlendStateDesc GetBlendState(Material material, IReadOnlyDictionary<string, long>? combos = null)

Parameters

material Material

The material.

combos IReadOnlyDictionary<string, long>?

Integer parameters overriding those of the material, as F_ features or S_ and D_ combos.

Returns

RsBlendStateDesc

Remarks

Guesses the blend state from material flags and a few known shaders.

GetInputsForTexture(string, Material)

Gets hardcoded texture inputs. If no mappings are found it will be a single guessed RGBA input.

public IEnumerable<(ChannelMapping Channel, string Name)> GetInputsForTexture(string textureType, Material material)

Parameters

textureType string

The type of texture to query.

material Material

The material containing the texture.

Returns

IEnumerable<(ChannelMapping Channel, string Name)>

A collection of channel mappings and their corresponding input names.

GetIntAttributes(Material, IReadOnlyDictionary<string, long>?)

Gets the integer attributes of a material combined with those of its shader, the material taking precedence.

public IReadOnlyDictionary<string, long> GetIntAttributes(Material material, IReadOnlyDictionary<string, long>? combos = null)

Parameters

material Material

The material.

combos IReadOnlyDictionary<string, long>?

Overrides for the integer parameters of the material.

Returns

IReadOnlyDictionary<string, long>

Remarks

Adds the attributes that material flags and a few known shaders would compile to.

GetSuffixForInputTexture(string, Material)

Gets the file suffix for a given input texture name.

public string? GetSuffixForInputTexture(string inputName, Material material)

Parameters

inputName string

The name of the input texture.

material Material

The material containing the texture.

Returns

string?

The suffix string for the input texture, or null if not found.

Remarks

Provides a filename suffix based on common texture type conventions.
