Shader LiquidLevel_Em_Bm_Rfr_Ci (Legacy)

The LiquidLevel_Em_Bm_Rfr_Ci shader has the following characteristics.

Explanation

• The reflection vector used to access the environment map is disturbed by the BumpMap.

• The UV used to access the refraction are disturbed by the BumpMap.

• This shader is intended to create Elux drop beads.

Colors

• Color1 = Mixes the refraction and the environment map based on the fresnel value.

• Color2 = Mixes Color1 and the environment map based on the brightness of the pixel taken from szWhitesCubeMap.

• Final color = Color2 + (Vertex Color * fVertexColorMul).

Input Data

NormalMap / HeightMap

Material ® BumpMap

UV Channel 1

• By default the texture is intended as NormalMap

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

• Dark colors indicate minimum height. Clear colors indicate greater height.

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.

szRealTimeCubeMap / szCubeMap

• szRealTimeCubeMap: ID of the CubeMap that will be created in real time using a $CubeMap Dummy Object.

• szCubeMap: The name of the texture that will be loaded and used as CubeMap.

• szRealTimeCubeMap and szCubeMap can not exist at the same time.

szWhitesCubeMap

• szWhitesCubeMap: The name of the texture that will be loaded and used as CubeMap to detect the brightness of the pixel.

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]

fRefractionBumpiness

• The displacement value of the refraction. This is used when taking the pixel of refraction. Even a small value can be enough.

• Default: 0.2

• Range: [0..1] (1 = fully bumped)

fReflectionBumpiness

• Amount of disturbance that the BumpMap will give to the normals of the object. This is used when taking the pixel of reflection.

• Default: 0.5

• Range: [0..1] (1 = fully bumped)

fFresnelExponent

• Exponent used in the calculation of the fresnel value. It is used for power upgrading.

• Default: 5

• Range: [0..inf]

fColorInterpolator

• The value for which Vertex Color will be multiplied.

• Default: 1.0

• Range: [0..1]

fRefractionIndex

• Index of refraction of the material.

• Default: 1.5

• Range: [0..inf]

fTextureSize

• The texture size used for refraction. This value is relative to the size of the back buffer.

• Default: 1.0 (1 = identical size to the back buffer)

• Range: [0..1]

fInterpolator

• Interpolation value.

• Default: 0.5

• Range: [0..1]

c3Color

• Color that will be multiplied.

• Default: 1 1 1

• RGB: [0..1]
