I'm trying to make a short animation in space and I need stars as my background. I found this nice tutorial, unfortunately it was made in blender render and doesn't work in cycles.
Can someone tell me how to recreate this in cycles?
First you need to jump over the the Node Editor view, then select Shader Nodes and World. Also make sure Use Nodes is checked.
Then add a Noise Texture node and a Color Ramp node. Plug the Fac of the noise texture into the Color Ramp, and the Color of the Color Ramp into the Color of the default Background shader.
You can then adjust the Color Ramp and Noise Texture how you would like to create the desired starry effect.
Shown above are the settings I used to create the below render.
