Maya for 3D Printing - Rapid Prototyping
In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

Any Facing Ratio Tutorials

Hey guys!

facing ratio creates the changing value, between 0 an 1. this value is creaed by the angle betwee the normal of the surface and the direction of the camera. i use it on anything that has transparency.
to test this u can create a plane and put a checker texture on it
make the texture bright colors, like red and white
then create a blinn, make the color 60%gray and make it 75% transparent. then render
now attatch a sampler info node's facing ration to the blinn's transparency RGB to see the difference

i think there are other nodes with facing ratio property, but i've only used with sampler info...
just check to see if other have that property
