All of this. I know what is glow parameter, I know what is optical FX. If i do a lens flare with them, both the starlight effect and the lens flare mysteriously appear in the middle of the screen, not on the object.But I think there may be options in the glow and optical fx params.
The paint fx stuff, unless you've converted to polys then pfx is a post effect and isnt actually rendered when your geometry is. It's done as a post effect and is added after the render is finished.
