You do have some control over transparency if that's what you are after. You can set the object to respond to black as a totally transparent color, or you can create translucency with GHOST OBJECT ON.
Combining GHOST with FADE OBJECT, you can control the intensity of the normals (that controls how an object is affected by light) and give the impression of controlling the objects transparency. In fact, paired with SET AMBIENT LIGHT 0, you could make an object slowly disappear.
Here's a basic example. There is a cube within a sphere. The cube is solid, the sphere transparent. Use the UP arrow to increase the FADE value thus increase the normals. Use the DOWN arrow to decrease the FADE value and ultimately reverse the normals. Use the RIGHT arrow to increase AMBIENT and use the LEFT to decrease AMBIENT light.
