Hi,

I am trying to render a sun ( star ) in space. But the results I am getting using a particle system are a bit disapointing.. The sun appears transparent and quite fake - I can make it look slightly more realistic by adding a few hundred particles, but that is not really an option..

Does anyone know a good method to render a sun? I think I am approaching this wrong...

Get a sun image from Nasa and put it on the screen. Smiley

To do bright suns well you need to use HDR rendering, or fake it and render a big glow or halo around it so it looks blindingly bright.

Would love to know this as well.

Currently the stars I do are created by a general algorithm of calculating the distance from the center of the star (creating a ball which get darker the farer out you go) and then considering the distance less considerable if near any 90 degrees or 45 degrees * n of circle considering from center.
