Description

3D #standard shader property; a linear list that indicates the manner in which each texture layer

blends with the texture layer below it.

The shader’s texture list and blend function list both have eight index positions. Each index

position in the blend function list controls blending for the texture at the corresponding index

position in the texture list. You can set all index positions of the list to the same value at one time

by not specifying the optional

index parameter. Use the index parameter to set the list one index

position at a time.

Each index position of the blend function list can have one of the following values:

#multiply multiplies the RGB values of the texture layer by the RGB values of the texture layer

below it.

#add adds the RGB values of the texture layer to the RGB values of the texture layer below it, and

then clamps to 255.

#replace causes the texture to cover the texture layer below it. No blending occurs.

#blend causes blending to be controlled by the value of the blendSource property, which allows

alpha blending.

The default value of this property is

#multiply.

Example

In this example, the shaderList property of the model named MysteryBox contains six shaders.

This statement shows that the value of the fourth index position of the

blendFunctionList

property of the second shader is set to

#blend. Blending of the fourth texture layer of the second

shader of the model will be controlled by the settings of the blendSource, blendSourceList,

blendConstant, blendConstantList, diffuse, diffuseColor, and useDiffuseWithTexture

properties.
