ADOBE DIRECTOR BASICS
3D: Controlling appearance
If you want the texture to appear to rotate around its center, you can set the textureTransform.position to vector(0.5,
0.5, 0), to place the uv point [0.0, 0.0] in the center of the shader. You will probably have to cut the texture into four
equal parts and swap the parts around to obtain the desired effect.
Adjusting the wrapping
If you set the textureMode of a given layer #planar, #spherical, or #cylindrical, then you can use the wrapTransform
for that layer to rotate the texture so that it fits the geometry of the mesh correctly. Only modifying the rotation or
axisAngle properties of the wrapTransform will have any effect. Altering the position or scale of a wrapTransform will
make no difference to the appearance of the shader.
Note: aShader.wrapTransformList[textureLayerIndex] has an effect only when
aShader.textureModeList[textureLayerIndex] is set to #planar, #spherical, or #cylindrical.
Layer property lists
The values for all the texture layer properties are stored in linear lists as part of the shader object.
blendFunctionList
blendSourceList
blendConstantList
textureList
textureModeList
textureRepeatList
textureTransformList
wrapTransformList
To get or set a given property for a particular layer, use: shader.layerPropertyList[n].
For example:
aShader.blendSourceList[3] = #alpha
put aShader.textureRepeatList[4]
The objects that store layer properties for a shader are not true Lingo lists. You cannot set the value of one of these lists
to a Lingo list. This command gives a Lingo list as the output:
put member("3D").shader(1).textureRepeatList -- [1, 1, 1, 1, 1, 1, 1, 1]
However, the command below will lead to a “Wrong Type” script error:
member("3D").shader(1).textureRepeatList = [1,1,1,1,1,1,1,1]
To set the values in all 8 layers of the shader to a given value with one command, use:
aShader.layerPropertyList = aValue
For example:
member("3D").shader(1).textureRepeatList = 1
Painter shaders
To explore the properties of the Painter shader, download and launch the movie ShaderTypes.dir.
See “Shader types” on page 35for details on how Painter shaders interact with lights. See “Toon modifier” on page 138
for a different way to achieve similar results.
