Oh sorry guys and thanks BB, I've only made something glow once (I made some makeup on V4's face glow) and indeed I did use Ambient and Alternate_Diffuse with a black and white image map to say what parts I wanted to glow... it worked fine.

So I guess the probe light is just for if you wanted the light bulb in a lamp model to actually illuminate like a real light, right?... Just clarrifying...

And I'm sorry, I guess I can't help, I'm not sure as to what else could be stopping it from glowing like the original promo's, unless it's a trick of lighting, or it could simply be that DAZ has different settings (obviously) and you simply need to change some of the Disp and Spec values??
