In this concise Blender tutorial, Charles demonstrates how to create a realistic night sky using procedural texturing. He starts by adding a plane and renaming a new material to "Night Sky." He replaces the default Principled BSDF with an Emission shader, connecting it to the Material Output. To generate stars, he adds a Color Ramp driven by a Noise Texture, adjusting the ramp to control star detail and brightness. He sets the Noise Texture's Detail to 4 and Scale to about 800 to define star density, then fine‑tunes the Color Ramp to taste. The workflow shows a step‑by‑step shading setup for a customizable night sky effect.

Hey everyone, Charles here for a new tutorial on how to create a procedural night sky in Blender. So the first thing you need to do is create a plane, then modify it the way you want it to look like. Once that's done, we go to the shading space and we're going to add a new material which we're going to rename Night Sky, then remove the Principled BSDF and instead add an emission. Connect the emission to the surface of the material output. Then we're going to add a color ramp, which is going to help us tell Blender how detailed we want those stars and how bright we want them to be. And we're going to connect to this color ramp a noise texture. So let's just change the color ramp to define how detailed and how clear we want our stars to be. Then we're going to change the scale to tell how many stars we want. We then increase the details to 4, and I'm going to change the scale. I'm going to put it up a little bigger, so 800, and change again the color ramp. Of course, you need to adapt to your taste, but that's basically how you do a night sky.
