Shader Txt_Bm (Legacy)

The Txt_Bm shader has the following characteristics.

Explanation

• This shader illuminates the pixels of the texture based on the normals on the bump map.

• It supports only one light, which is managed as omnidirectional without range.

Code example

This is an example of Txt_Bm shader.

$Shader

{

szName = Txt_Bm

szLight = Omni001

}

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.

NormalMap / HeightMap

• By default the texture is intended as NormalMap

• Material ® BumpMap

• UV Channel 1

• To use a HeightMap, name the texture xxx_hm.xxx. This will be converted inside the engine into a NormalMap.

• Dark colors indicate minimum height; clear colors indicate greater height.

• The Alpha channel must contain Gloss Map values. The Gloss value enhances, or scales, specular intensity for pixels. If the gloss value is zero, the pixel will not have specular quality.

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

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.

szLight

• Name of the light that will illuminate the object. If not specified, the result will be unpredictable.

fHeightMapBumpiness

• Bumpiness when the bump texture is a HeightMap.

• If multiple objects share the same HeightMap, the value of fHeightMapBumpiness will be the value of the first object that will load the texture.

• Default: 10.0

• Range: [0..inf]
