This is a paid asset, but we’ll share Simple Sun Shader Free for you. Enjoy!!!
Simple Sun Shader v1.2
❶ Shader has 3 variants: basic, dual color, and textured.
❷ Animates smoothly and looks great at any scale using a 256×256 noise texture, and you can reduce the size further without notably harming the appearance (even 32×32 works).
❸ Many parameters are exposed for tweaking and a script is included for easy access to properties and keywords.
❹ Suitable for low-end mobile devices. The showcase video was recorded on a Nexus 5 at 60 FPS.
❺ Renders using a single quad and can be used in particle systems.
You can download the showcase video in HD from here.
Praise the Sun.
