Fluid flow - Macromedia Director 3D

Have been doing a few 3D hydraulic pumps in 3DS Max for training purposes. My boss has just decided to make one interactive to show how the fluid pressure affects the pump. I have done interactive stuff in SW3D, so I don't have a problem with how to create it, but I can't think of how to make the fluid look like it is flowing down the pipe (in Max I was just using an animated material map which doesn't work in SW3D because it's procedural).

    Default Fluid flow

    Have been doing a few 3D hydraulic pumps in 3DS Max for training purposes. My boss has just decided to make one interactive to show how the fluid pressure affects the pump.

    I have done interactive stuff in SW3D, so I don't have a problem with how to create it, but I can't think of how to make the fluid look like it is flowing down the pipe (in Max I was just using an animated material map which doesn't work in SW3D because it's procedural).

    Anyone got any ideas? I'm looking for the simplest way if possible.

    I have seen a tutorial about using animated textures in SW3D - it says to create a new texture at run time using an animated media cast member & assign it to the shader. Any other ideas I'm overlooking?

    I also would like to gradient the colour of the fluid to represent the change in pressure as it travels along the pipe (in Max I used a self illuminated gradient on the material).

    Thanks in advance,

    Dave Lock.

    The simplest way might be to swap out several models making them appear then disappear in a sequence though I have only been working with Director for a month and there might be a way to animate textures using Lingo.

    In Director self illum is called emissive color and is a shader property. It
    can be tweened by code from one RGB value to another.

    You can animate the texture of a given shader from a series of bitmap cast
    members.

    Check the "Emissive Color Tweening" and "Texture Animation" in the Chrome
    Lib set of 3D behaviors:

    Also take a look at textureTransform()

    Agustín is right. You can also make a texture move by offseting its
    transform over time. Check the "Texture Scrolling" behavior in the same lib.
