Ok, guys, now I had Was's job working (thank you sooooo much man, I owe you and Dune barrels of beer). I understand that to make an object semitransparent I do need to mask it according that procedure.
But how can I get a mask from an image map out of the object I have to make semi transparent?
In other words I have to make an airplane canopy. The canopy is a 3d object, not a flat one such as the card in Was's example. How can I mask that canopy?
I know, I know that this is a rookie question, but I did not find any tutorial nor explanation about it.
Thank you guys!
