Reflection map? - Macromedia Director 3D

You know the Opel Sigma demo at Chromelib.com. It uses some kind of reflectionmap that reflects the eviroment when you turn the camera. When I try to do this i 3d studio max, it doesnt behave as I want it to do. If I rotate the camera, the reflection is the same from every angel. Why I dont want it I want to be like that demo. Cheers...

    Hello,

    The model in the Chrome Lib Opel Signum sample has been created under 3DS
    Maxa and its environment map has been directly set in the MAX material
    editor. The Shockwave 3D exporter does take these settings into account.

    Quoting this article on macromedia.com:

    Preparing 3D content for Shockwave 3D Texturing and mapping
    [url]http://www.macromedia.com/support/director/work_3d/models_use_in_sw/models_use_in_sw04.html[/url]

    * Using reflection and refraction maps:

    Reflection maps export properly in Shockwave 3D. Refraction maps export, but
    do not produce a refraction effect; instead, they appear as self-illuminated
    specular maps. When applied, these maps export at full force; varying the
    percentage or density within the 3D application has no effect. This means
    reflections may block out the diffuse color or map.

    This could have been done by code as well:

    Example from the manual:
    member("3DPlanet").model("GlassSphere").shader.ref lectionMap =
    member("3DPlanet").texture("Portrait")

    Best regards,
    Karl Sigiscar.

    The Opel Sigma doesn't reflect the envionment. It has a pre-generated
    reflection map whose normal coordinates are always turned to the camera.

    If you have a sphere with a reflection map, and you rotate the model, you will
    see the same fixed texture from any point of view. You will need a non-sphere
    model (like a car) to see the deformation effect of the texture.

    Hello,

    how can i create this "pre-generated reflection map" in studio max?
    I try the reflection slot, but the problem: "This means
    reflections may block out the diffuse color or map."
    But i see the Opel Sigma, so i want this reflection.
    Anybody can help me?

    (Sorry my veryvery bad english...)

    I have barely worked with reflection maps so would also like to know advanced
    techniques with them. There might be tutorials out there with source to
    experiment with. One day, I will look for/at them :)
