Renderman 21 Opacity Maps Tutorial

A very quick tutorial on how to apply an image to a plane and have Renderman ignore specific parts of the image. First I'll go over how to create a transparent background for a leaf in Photoshop, then we'll jump over in to Maya to hook it all up for rendering. Finally I'll discuss some pros and cons of this method and give another example of how you can use it. I got the leaf image used in this tutorial here: http://seamless-pixels.blogspot.com.au/2012/09/leaf-textures.html Check out more of my stuff: http://instagram.com/smallrobotstudio http://smallrobotstudio.com
