EDIT:boogers! the title can’t be edited!!!
I’ve tried a half a dozen different versions of Blender ranging from 2.67 to 2.69 RC2 and also on both Windows and MacOS and the output of every attempt is a black object.
I’ve tried several basic scripts including the one on the Blender wiki for OSL and none of them work. They compile, but as I said, the output is black. All the other nodes work fine, just not the script node.
Am I missing something obvious here?
Solved: There is a checkbox under the render settings for Open Shading Language. Silly I assumed Cycles was OSL by default. Now I’m both more confused and less confused which is confusing.
