Formerly a world material now an add-on.

A fully procedural sky system containing a World node-graph and sun and moon rig that dynamically transitions between day/night and evening/morning. Works in both Eevee and Cycles and can be used as HDRI alternative. Fully customizable colours using a simple ramp setup to determine sky, clouds and sun colours. Clouds can be easily controlled and animated and emulate shading with shadows and highlights.

Perfect for fantasy, cartoons and semi-realism. Add turbulence and softness to depict wispy clouds or increase density and darken shadows for a dramatic stormy sky. Created for artistic control, not scientific accuracy, this sky setup is infinitely versatile yet carefully guided as to not produce overblown results. Simply tweak parameters and colour ramps in the world material. 

The Sun Rig uses a sun light object to drive the position of a visible and customisable sun in the world shader. The rig itself ensures its angle is always in relation to the scenes centre and therefore the sun can be placed at any location with any need for manually rotating it. The suns angle then becomes the driving factor for the day/ evening or morning colour modes.

• Fully integrated with Blender's built-in Sun Positon add-on.
• Make your own presets
  
• Comes with 18 diverse presets
• Viewport quick menu can be called with a custom hotkey
• Auto lights automatically enables/disables Sun and Moon and strengths depending on sun position
• Customize Sun, Moon, Stars and Clouds colours and shapes.
• Cell shading for animation style
• No need to use shader graph, all parameters exposed in the world tab

NOTE: Each Blender scene will support a single Sun and Moon lamp, therefore its recommended that if using both night/day skies, they should be setup in separate scenes.
