This Tutorial is for those who have Red and Cyan 3D Glasses and want to make their models come out of the screen and appear over 9000 times cooler than they actually are.
1.) Render your ZBrush Model in Perspective.
2.) Export your Document as "_insert name here_Right.psd"
3.) Rotate your model to the left just a small fraction, so that the rotation distance is as if it is the distance from right to left eye.
4.) Export this Document as "_insert name here_Left.psd"
5.) Open up both images in Photoshop and copy the left image into the right image as a New Layer. (So that the left image is above the right image.)
6.) Double click the Left image in the layers panel so that the "Layer Style" box pops up. Uncheck the "R" Channel, so that the Left Layer appears to be only Red. (For some reason when you uncheck the R Channel it removes the Green and Blue channels).
7.) Click OK and save your image! It is now Red and Cyan Anaglyph 3D!
Please note, The Red side of the glasses is LEFT, and Right is Cyan
