A trans(parency) map is just like a texture map

• except that ...
  it is used to "hide" or "show" certain areas of the object being rendered. (i.e., make areas transparent)

Note**
Where the transmap is BLACK, the object WILL NOT be visible.
Where the transmap is WHITE, the object WILL be visible.

Colors in a transmap (other than black and white) have no meaning. An exception to this is that varying shades of grey will give varying amounts of transparency.

Try this ... (using your favorite "paint" program)
Take a texmap for an object ...

1. make a copy
2. convert it to black and white (or grey scale)
3. save it (use a different filename so you don't overwrite your texmap)
4. then (in the "Surface Material" window) load it as a transmap and ...

Set "Highlight Size" to 0%
Set "Transparency Min" to 0%
Set "transparency Max" to 100%
Set "Transparency Falloff" to 0.0

... see what happens.

Also, you may have to convert the transmap image to a negative image to achieve the desired results. (See note** above)

Hint: make sure you set the "highlight" to BLACK (and zero) for the object using the transmap or the highlight will show up on transparent areas when you render.
