Tutorial: Dynamic Earth Day to Night in Cycles


You've already seen plenty of planet modeling/texturing tutorials, but have you ever tried to have it transition from day to night?

To create a dynamic day to night transition for Earth or any other planet in Cycles, we’ll need to get the rotation data of the sun and plug that into the normal value of the sphere.

We can do this pretty easily by adding drivers to a mapping node between the input geometry node and the normal node.

I have a LONG history with Blender – I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-)
