This class in other games:

UT2003, U2XMP, U2, UE2Runtime

Shaders can change a material's opacity mask, apply a specularity and/or light map and a detail material. Unlike Combiners or TexModifiers, shader changes to a material will be lost if the shader is used in another shader or combiner.

Properties

Property group 'Shader'

Detail

Type: Material

Modifiers: editinlineuse

A material that is overlayed onto the diffuse channel. The detail material is scaled according to the DetailScale value. The visibility of detail materials is controlled by the DetailTexMipBias entry of the section for the current render device in UT2004.ini.

DetailScale

Type: float

Scales the detail material, if specified. The detail material's size is divided by this value.

Default value: 8.0

Diffuse

Type: Material

Modifiers: editinlineuse

The diffuse channel of the shader. This is required unless SelfIllumination is specified without a SelfIlluminationMask, in which case Diffuse is ignored.

ModulateSpecular2X

Type: bool

Opacity

Type: Material

Modifiers: editinlineuse

The opacity channel of the shader. The alpha channel of the specified material is used as opacity of the diffuse channel. If the opacity channel is specified and is different from the diffuse channel, then only BitmapMaterials and ConstantMaterials are allowed. These may also be run through one or more Modifiers.

OutputBlending

Type: EOutputBlending

Specifies the shader's output blending mode. See EOutputBlending type for details.

PerformLightingOnSpecularPass

Type: bool

Unused. Has no effect whatsoever.

SelfIllumination

Type: Material

Modifiers: editinlineuse

The lighting channel of the shader. If no SelfIlluminationMask is specified, this material is used instead of the diffuse channel as the result of the result of the shader, which then is rendered "unlit".

SelfIlluminationMask

Type: Material

Modifiers: editinlineuse

A mask for the lighting channel of the shader. The alpha channel of this material determines, how much and which parts of the SelfIlumination material is applied. This can be used to e.g. make some parts of a surface unlit, while the other parts still use the regular lighting.

Specular

Type: Material

Modifiers: editinlineuse

The specularity channel of the shader. This material is applied over the diffuse channel to create shining effects. The specularity channel is ignored on 3Dfx cards.

SpecularityMask

Type: Material

Modifiers: editinlineuse

A mask for the specularity channel. The alpha channel of this material determines, how much, and which parts of the specularity Specular material is applied.

TwoSided

Type: bool

Specifies whether surfaces using this shader should be rendered even if viewed from behind.

Wireframe

Type: bool

Specifies whether only the borders of surfaces using this shader should be rendered. If applied to a meshes, the wireframe model of the mesh is rendered.

Internal variables

Instance functions

Reset

function Reset ()
