Hi williams.7489,
Without a scene file that contains this material, I can’t tell what you have set up.
When you apply the material to an object, you get a Material Tag. Click on that Tag and go to the
Attribute Manager> Coordinates> Rotation.
I can’t tell you without a scene file what axis you need to rotate or if that is possible with your set up.
(Think of a noise shader set to World, then it would not work. Similar to that, if you use noise in your set up, check the options there.)
If you need an upload link, I’m happy to look into it.
Perhaps it could be solved as well by selecting the UV mesh and rotate this. Not really the way to go, but an alternative I like to mention.
All the best
