3d text trick

On a new comp, type your word.
Pre-render and use the pre-rendered version and duplicate the layer about 10-20, depending on how good you want the text to look as 3d.

Then make all of them 3d (the little 3d box). Use the last digits on the Position line and change all f them to a different number. I used 5.0, 10.0, 15.0 and so on until I was finished.

Then bring that comp into your main comp and press the little star (Collapse for transformation) because at firs you won't be able to see what you did, but you need to click that button in order to see the changes. After clicking that button you have to make that text comp 3d. You then toggle with the figures in the last row on the X,Y and Z positions and see your 3D text in action.
