Right now I'm developing a relatively simple first person game where you are standing at the end of the tunnel of light saving the souls that come through before they get past you and enter hell. Broken down into programming speak, the souls are spheres. There is also an orb (sphere) on each corner of the "arena" that randomly attacks (shoot small fireball like spheres) at the player (you).
Right now they look rather primitive and plain. They are textured, and I experimented with cull and shosting and lighting effects, but they still all just like fancy spheres. I want to add some glowing aura of sorts around the soul and some fire-effects to the fireballs. How would I go about doing this?
I've experimented with using constantly rotating plains textured with partially transparent areas that are oriented to the soul or the fireball, but then they just look like spheres with 2d plains rotating about them. It still looks cheap. Any way to create 3d explosion or aura effects?
