Shader Txt_Lm_Lc (Legacy)

The Txt_Lm_Lc shader has the following characteristics.

Explanation

• This shader makes a linear interpolation between [Texture * Lightmap, Lightmap].

• The value of the interpolation is given by the product of the alpha channel value of the lightmap for the fAlphaMul parameter: interp = Lightmap.a * AlphaMul.

Code example

This is an example of Txt_Lm_Lc shader.

$Shader

{

szName = Txt_Lm_Lc

fAlphaMul = 0.5

}

$Shader

{

szName = Txt_Lm_Lc

fAlphaMul = 0.85

iClipMap = 64

}

Input Data

Texture

• Material ® DiffuseMap

• UV Channel 1

• Alpha Channel. If the bAlphaTransparency or bSolidAlphaTransparency parameter is True, it impacts the pixel opacity.

• Must contain the Gloss Map values in the Alpha channel. The Gloss value scales the intensity of the specular. If the Gloss Map value is zero, the pixel will not have specular.

• The Gloss value is also used for reflectivity. A value of 1 indicates total reflection. This value is multiplied by fReflectivity.

Lightmap

• Material ® AmbientMap

• UV Channel 3

• Alpha channel used to indicate the contribution of each pixel on the final pixel.

Parameters

bObjectSpace

• Explicitly indicates whether this mesh will be exported to Object Space or World Space, regardless of export parameters.

• If this parameter is not present, the export parameters will be used, otherwise they will be overridden by this value.

• Default: The export parameters are used.

• Range: True / False.

fTransparency

• Transparency level of the mesh.

• Default: 0.0

• Range: [0..1] (1 = completely transparent)

bDoubleFace

• Duplicate the faces by flipping the verse.

• Default: False.

• Range: True / False.

szAnimatedTexture

• Indicates that the texture will be animated using the specified Animated Texture ID.

• Default: Null.

szAnimatedLightmap

• Indicates that the Lightmap will be animated using the specified Animated Texture ID.

• Default: Null.

fAlphaMul

• Lightmap alpha channel multiplier.

• Default: 0.0

• Range: [0..1]

iClipMap

• The pixel is drawn only when the value of the texture alpha channel is greater than iClipMap.

• If (alpha> iClipMap) ® render_pixel

• iClipMap, bAlphaTransparency, bSolidAlphaTransparency can not exist at the same time.

• The clipmap is not active in the case of reflective material

• Default: -1

• Valid values: -1, [0..255] (-1 = clipmap disabled)

bAlphaTransparency

• Activates alpha transparency by pixel. The value of the alpha channel of the texture indicates the opacity of the pixel.

• A pixel value of 0 indicates total transparency; a value of 1 indicates total opacity.

• bAlphaTransparency and bSolidAlphaTransparency can not exist simultaneously.

• Default: False.

• Range: True / False.
