How do you add a custom sky shader?

Question

I've modelled a solar system this afternoon and I thought I'd write a sky shader for stars and nebulae and whatnot but for the life of me I can't work out how to attach a shader script to an environment shader... There's good documentation which is crystal clear:

https://docs.godotengine.org/en/latest/tutorials/shaders/shader_reference/sky_shader.html#

I tried duplicating another shader but it throws a wobbly at shader_type sky; plus it won't load. There just doesn't seem to be a "shader" option that I can see. I'm on 3.4.4 which I think is the latest.

Sorry guys, I'm clearly missing something super obvious here, if you could help me out I'd appreciate it.

Answer 1

A core team member just kindly clarified; it's Godot 4 only. I'm really confused as to why it's in the "latest" docs. I thought "latest" meant "production" (3.4.4 at the time of writing), is that not the case?

Regardless, I hope that clarifies for anyone else seeing the functionality in the docs and hitting a brick wall in 3.x. I'll port the project over to alpha 8 and have a play with it.
