# How can I animate my Cycles shaders?

For a scene, I have to change shader parameters (using nodes in Cycles) as time goes on in the scene.

I've looked for a node that inputs a time sweep or frame number, but neither is available in Cycles. Am I looking in the wrong place? Or is there a workaround/trick I don't know about?

If you want to do this often and want to be even faster, you can also always just press I (as in "Insert Keyframe") while your mouse is over basically any value field/button/dropdown/selector/... in Blender and it will insert a keyframe for your current frame.
Press AltI to remove it again.
