I have this problem, which I think might be a bug. I would like to keyframe environment texture so I can change lighting easily by sliding the timeline.
So I connected texture coordinate and mapping nodes to environment texture. While Im changing the Z rotation value manually, it works fine. But if I set keyframes to Zrot value, it does show that yellow/green bg behind value and even the value is changing while Im moving on timeline, but the actual texture won’t rotate along.
Is there any workaround to get this working? I’m using 2.79.
