Dont think so - you would need to set up lights in some way, really.

Good news everyone! I really am THAT good...

You could use a semi-transparent 'shell' ontop of the object. Maby?

Sounds like a good way to do it.

What about glowing lights on buildings/aircraft/spacecraft? Most games use a flat polygon that always orientates itself face-on with the reviewer. The bitmap is just a black square "glowing" and transparency. Hidden and Dangerous/Hardwar had a lot of similar lighting. Any one been able to do this? Is there a special name for it?!

I have done this quite a lot in DB1 and it works well, if your textures are good enough. Photoshop has plenty of filters and plugins to do this well

How's about this for an idea:

Rather than placing the "glow" polygon in the 3D world and have all the problems associated with that why don't you keep it 2D?

By this I mean you can set up a 2D sprite with an appropriate texture, make it semi transparent and then put it on top of the glowing 3D object when it's on the screen and hide it in other situations. You can use the screenx(OBJnumber) and screeny(OBJnumber) commands to work out where to put it. You could also scale it depending on how far away the glowing object is from the camera. Most programs don't scale the "glow" sprite, though (like Unreal Tournament, Aliens versus Predator and so on).

Check out that TRON light cycles demo. The character in that glows, it was written in Dark Basic.

Watch out that pasting does not slow down your 3D fps.
