I was trying a osl shader. For the animation i would like to change the material over time. In the documentation on the wiki also for 2.6 there is mention of a time node. If I look in the node editor add->input not such node. Any ideas. [/img]

Ah got the solution. You can just right click the field you want to animate in the node editor and insert a keyframe. Like everywhere else . So simple I did not think of it. No time node necessary. Maybe consider giving the documentation an update.
