It's a glowpoint (texture is missile_flare), which should be placed where the thruster is, with no normal. You'll have to experiment with the size, but the values I've seen indicate that the glowpoint may have more than 10x the radius of the thruster.
so basically if I use a glow point with no mipmaps, then I'm supposed to have the flare visible from close and far ranges right? this dosn't work, as I've tested it extensivly... the glow is only visible when viewed from the back of the missile...
The glowpoint, if blowfish is to be trusted, should have no normal...
And if you want it to fade in like the ones in the mediavps, it should have mipmaps which (afaict) are basically the normal sort of mipmaps, for every LOD (mipmap lod, that is) but the 0th (full-resolution) LOD, which should be black.
Edit:You have to set the glowpoint's normal to 0:0:0
I was going to guess that's what you meant by 'no normal', but considering for all I know specifying a normal might be some completely optional thing... ah well, you beat me to it
