Glass bottles etc. - Macromedia Director 3D

Hi, I'm having problems trying to create glass effects. I've created a bottle and I want to make it look transparent and have labels on it. I have the effect that I need except the bottle is solid. Is there any examples that I can look at? Cheers for any help on this. Simon....

    There's a number of ways of doing this:

    You can set the 'blend' property of a shader, to make the whole shader
    transparent.

    Alternatively you can set the blendFunction and blendConstant of an individual
    texture layer within a shader.

    A third method would be to use a texture image which contains an alpha
    channel. For this, ensure the textureRenderFormat is set to #rgba8888 so that
    you have 8 bits for the alpha channel (rather than the default 1 bit).

    For more info look up all these in the director help: Shader -> properties,
    blendFunction, blendConstant, textureRenderFormat.

    Hope this helps!

    Glass can be a tough effect to get right.

    With a mixture of multiply blendFunction mode on the reflection map, and
    setting up suitable ambient, diffuse and specular colours, it's possible
    to get a fairly good glass effect.

    Here's an example of one I was involved with several months ago ( the
    actual content itself is very simple, but you'll see the glass effect if
    you grab and drag the mouse to rotate around the item containing the
    spinning vanes )
