Doug, use a black and white transparency map.

I'll use a bar 1.8 meters in lenght on the X axis for this example.

1 In paint brush create a black and white brush the thinner the better
    (less memory usage) that's black(left) to white(right)
    Note: In the Transparency map White is Transparent Black is Opaque.
2 Load this image into lightwave.
3 Under Surfaces select the surface name you gave to the bar.
4 Click on the "T" to the right of Transparency (%)
5 Texture type should be Planar Image Map, Texture Image should be
   what ever you named the black and white brush you just created, Texture
   Axis should be Z.
6 Click on Automatic Sizing then click Texture Size. Make a note of the X
   number (1.8M in this example) and double it and add .1 (3.7M in this example)
   (you want your map just a little bit bigger that twice the X length of your objcet)
   Y and Z are ok
7 Click on Texture Center and make X minus half of the length of the object plus .02
   (-0.92 in this example). (This will allow the entire object to be tranparent at first).
8 Click on Texture Velocity and enter a figure in X that such as .06 this will make the
   bar slowly appear over 30 frames (1.8 length of object / 30 frames = .06 Velocity per frame)
   You'll have to play with this to get the desired effect.

Congratulations you now have a horizontal bar that will slowly appear over 30 frames
Hope this helps.
