Missing Open Shading Language in Cycle Renderer Check Box Was reading up some interesting answers on animating noise. Until, I found out that blender 2.75 doesn't have the same interface as shown on the image below.

Does anyone know how to turn on Open Shading Language in the cycle renderer? Following the post here How to animate noise texture &quot;seed&quot;? I was not able to see the noise on screen at all. It outputs the noise as plain white.
OSL isn't available on GPU. If you are already set to CPU, it's possible your version of blender was compiled without it. Are you using an official build from blender.org? (btw, any particular reason for using 2.75? The latest version is currently 2.76) – gandalf3
