Custom Sky Plugin - Showcase

Tested it on 1.19.2 - for me it does not have flaws. For vanilla or custom biomes and/or dimensions dependent, it can be done entirely with procedures (no code required).

Comet test (it allows layers) - Does not require additional coding.

  With additional coding (manual coding - requires a few changes), I implemented it to 1.19.3. Also it works for day or night skybox (with additional code). 

I have been trying to do this for a long time, with little success. 

Now it is possible ... Special thanks to sumeshi0216
