    Default Propeller spinning problem

    I have a model of a plane and need to make the propellers spin at a realistic
    speed.

    I've tried creating the animation in 3DSMax, importing into Director, and
    altering the playrate to try and make them spin faster - but no success. As I
    increase the playrate the animation seems to badly and not spin.

    The animation has a 5 frame keyframe loop with 1 rotation of the blades. When
    exported the animation doesn't seem to play at the same speed as in 3DSMax,
    i.e. plays slower.

    I've also tried Director's 'Automatic Model Rotation' function but this has an
    upper rotation speed limit of 20 which is no where near fast enough.

    Is there another way to rotate the model either in Director or 3DSMax which
    will give accurate results?

    If you are using the same Automatic Model Rotation that I have in my
    library (the built in one that comes with Director), the default speed
    is 5 and you can increase it up to 20 (or decrease to -20).

    If 20 is too low for you, then you can change the max/min in the script
    itself. Open the script and scroll down to line 412. Change the #min
    and #max to whatever you want.

    If you want the -look- of a rapidly spinning propeller (circular, blurry
    vibration...) you might want to use a blurry spinning texture instead of a
    spinning model. Use a circular, mostly-transparent alpha texture on a shader,
    and spin it over time. Something like
    yourScene.shader("propeller").textureTransformList[x].rotate(0.0, 0.0, 2.0).
    Might look better, just a thought.
