While this would be helpful and does have a lot of potential uses, it’s unlikely this will ever be added to the skybox system. Reason being, Roblox is more focused on their upcoming procedural skies which will be much more dynamic and customizable.
“Our big sky direction is moving more towards procedural skies rather than tactical features around skyboxes.”

This has also been recommended a few other times:
- I'd really love to be able to rotate a skybox
- Skybox rotation
- I want to rotate my skybox
- Sky.CFrame to rotate and move the skybox, and ability to layer skyboxes ontop eachother
This is definitely something people want which is why I’m hoping we’ll get rotation with the procedural system, but I think adding new features to skyboxes doesn’t make a lot of sense given how ancient it is and that it would distract Roblox’s engineers from finishing the new skies.
