Shader Vc_Sp_Lit

The Vc_Sp_Lit shader has the following characteristics.

Explanation

• Applies lighting in real time to the object and multiplies it by the vertex color, then adds specular.

• Supports two lights, which are managed as omnidirectional without range.

Colors

• ColorD = Vertex Color * (AmbientColor + NLuci (diffuse_term * DiffuseColor * LightColor))

• ColorS = NLuci (specular * LightColor)

• Final color = ColorD + ColorS

Code example for one light

This is an example of Vc_Txt_Em_Fr shader with one light.

$Shader

{

szName = Vc_Sp_Lit

szLight = Omni001

}

Code example for two lights

This is an example of Vc_Txt_Em_Fr shader with two lights.

$Shader

{

szName = Vc_Sp_Lit

szLight = Omni_Rossa

szLight = Omni_X

}

Input Data

Vertex Color

• If there is a valid Radiosity solution on this object, the vertex color is taken from the solution.

• If a Radiosity solution is not present or invalid, or if the bWireframe parameter is active, the vertex color is taken from the properties of the mesh. Therefore, the vertex color will be the color of the mesh.

Ambient Color

• Material ® AmbientColor

Diffuse Color

• Material ® DiffuseColor

Specular Color

• Material ® SpecularColor

Specular Intensity

• Material ® SpecularHilights ® SpecularLevel

• Increases the intensity and the size of the highlight.

Specular Glossiness

• Material ® SpecularHilights ® Glossiness

• Increasing this value increases the "shininess" of the object, so there will be a narrower highlight.

Light Color

• Light ® Color

• Color for every light

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.

szLight

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