Blender Cycles: Procedural Stars World
Hi everybody. Today I'm going to show to you how to make a stars world for cycles. Blender internal has an option in the world settings to create this, but cycles engine hasn't. So I have created a procedural world including galaxies too. First of all we need a texture to show stars. I have taken one node setup from this awesome apple material explained here . It is well explained by its author. It is called Big Dots . Then I need a noise texture to simulate galaxies in astronomy pictures. I have used the following. It is called Noise0Pattern : The next step is setting the noise texture on the world. I have used two Noise0Pattern groups, one for blue/pink light, and another for yellow light. I have also used alpha to be uses as factor for mixing both textures. This is what I have done: I have tweaked the pink/blue color ramp node to establish high and low density areas of stars in the world. After this I can add stars with different sizes and intensiti...
