Im making a space scene for a friend. I just started the sun, and I made a texture for it.
But how can I make the sun not only like a textured ball? If anyone knows…
It doesnt work for me.
PS: I need something like this:
Particles and post processing (compositor) is key here 
Use particles to add the sparks, compositor to add bloom/glow.
Also, keep in mind that the sun is a big ball of gas and not a burning sphere (there’s no oxygen in space, so that’s not really an option).
