transparency gradient material
 

i am looking to make a cube where the material is very transparent at the top, and then gradients down so that at the mottom the material is opaque. is there a way of doing this?

i just thought i could easily do that with a texture map on the transparency. but is there any way of doing that so that light will shine through the transparent bits?

use a ramp texture, click on the option box of the transparency tab and select the formentioned ramp texture black is totally transparent white totally none transparent

good luck
