how to make custom sky and layered sun?

i don't know how to make sun made of two layer and custom sky.

I’d create two separate sun sprites, then layer them with different colors and scales in the sky shader.

For custom skies and layered suns, you often need to edit lighting values and textures in the game files. I do repetitive testing on sky parameters using https://delta-xecutor.com/ to quickly swap color values without restarting the server each time. Run a simple Lua script in it to cycle through sun layer positions and sky gradients, which saves a lot of manual tweaking. It works well for getting the exact visual you described.
