| Adding this space dust to a space scene will improve how it looks and increase detail, making it look less plain. It also renders very quickly, so it will have virtually no effect on render times. (These pictures being posted took 3 to 4 seconds to render at 'best' Anti-aliasing level). Previously, I was trying to create space dust using pyrocluster, as well as with volumetric lights with noise, however, I did not get satisfactory results (all I got was long render times). After trying to find an alternative to the problem, I created this, and was very happy with how it turned out. A omni light (included) is used to illuminate this sphere. The omni light is set to only affect the Space Dust object, and nothing else. IMPORTANT: make sure you add the Space Dust object to the exclude list in any other lights in the scene! Otherwise, they will most likely make it appear too bright. The included omni light should be the only one illuminating it. Stars can be used along with this Space Dust for even better results. (I usually use the Sky Plugin to create the stars). No picture textures are needed for this, so there are no breaks in the textures (like what would happen if there was a texture that wasn't seamless). By the way, the color can be changed to your liking in the material editor. This space dust includes an alpha layer and transparency, so you can see stars through it. |
