Procedural Sky Stars — a procedural starfield sky shader for Godot 4. A multi-layered star field with smooth movement and natural, unsynchronized twinkling — no textures, fully GPU-based.

Features:

• Each star twinkles on its own rhythm (random phase and speed)
• Slow sky drift — a sense of gentle movement through space
• Fully customizable: space color, star brightness, twinkle speed, movement speed
• No textures — lightweight, fast, fully procedural

How to use:

• In your WorldEnvironment node, set Environment → Sky → Sky Material to a new ShaderMaterial.
• Assign SkyStar.gdshader as the shader.
• Adjust the exposed uniforms in the Inspector to taste (space color, star brightness, twinkle speed, movement speed).
