member(whichCastmember).model(whichModel).shaderList{[index]}.\

blendSource

Description

3D #standard shader property; indicates whether blending of the first texture layer in the

shader’s texture list is based on the texture’s alpha information or a constant ratio.

If the shader’s

useDiffuseWithTexture property is set to TRUE, the texture blends with the color

set by the shader’s

diffuse property. If useDiffuseWithTexture is FALSE, white is used for

blending.

Each of the other texture layers blends with the texture layer below it. Use the

blendSourceList

property to control blending in those texture layers.

The

blendSource property works only when the shader’s blendFunction property is set to

#blend.

The possible values of this property are as follows:

#alpha causes the alpha information in the texture to determine the blend ratio of each pixel of

the texture with the color being used for blending (see above).

#constant causes the value of the shader’s blendConstant property to be used as the blend ratio

for all the pixels of the texture.

The default value of this property is

#constant.

Example

In this example, the shader list of the model named MysteryBox contains six shaders. This

statement sets the

blendSource property of the first texture used by the second shader to

#constant. This enables the settings of the blendConstant and blendConstantList properties.
