Graphics certainly don’t make a game… so why bother with cool fx like volumetric nebula? Good question. I want to ensure I start out with a solid particle system that is flexible enough for numerous things in the game. Things like nebulas, engine trails, missle trails, lazers, explosions, clouds on a planet surface. So far I’ve been able to tweak the setup for most of those things. Here are a couple shots of a nebula during development.
