incidence angle (shader)
 

hey i m back !!!!!!!!!!!

yes i m back with a new problem with shaders. How can i create a shader or material who depend on camera angle ( an angle incidence) like velvet ?
wait for your answer.

use samplerInfo node. You create it by going in to general uitlitys and then drag and drop it on some Ramp shader. When connection editor opens (select other on a small pop up if not) select facing ratio and conect it to V cord of Ramp now your ramp (in Black and white) controls what ever you like Reflection, difusion based on facing to camera. see pic.

hope it helps
