How to make an object transparent In the render result, I'd like to be able to see the DNA inside the football.



How can I make the football transparent so that the DNA is clearly visible inside?
To do this in Cycles, choose cycles render and open node editor.

Create your base material for the football (this should be what it should look like if there wasn't any transparency on it.



Then mix this with a transparent shader, and make any necessary shader tweaks to give it the appearance you're looking for.



The cylinder is positioned inside the sphere, the cube behind it

Please keep in mind that if you prefer to use the Blender Internal Engine, that's perfectly fine, this is just a way to do it using Cycles.
