Change color and pattern for 3D object

[woffie]

I'm quite new with Director and Lingo and now I have a problem working with 3D
object. My question is, Is it possible to change color and pattern for a 3D
object with lingo script? If it possible, how it works?
For example: I have a sphere, I want the sphere to change color to red. And
the sphere also have a dotted pattern.
Can anybody help?

You can change the color only by setting the .ambient property of the shader of
your sphere model. To give it both color and spots, you need to set the
texture of the shader.

You can find a move that demonstrates this at:

Textures and shaders have a large number of properties. To achieve certain
effects, you need to combine the settings for different properties. To got to
grips with all this, download the file at...

... and place the three Director files it contains in your Xtras folder. You
will then be able to open the Shaders movie from your Xtras menu, and
experiment with all the different settings.
