In my custom dimension I want to have a custom sky with the 6 sided texture for it, how would I do this?

I want to make a custom sky, moon, sun, fog, etc. How would I do this?

I wanna make a corrupted block in my minecraft mod and I was wondering how I would do that with a playertickevent or detect if the block was placed and go from there? (This is forge 1.20.1)
