Glowing parts?
Glowing parts?
(OP)
I'm trying to make part of a model look as if it is made from the same sort of material as glow stars, so it sort of gives of it's own glow. is this possible? any suggestions would be great. Thanks again.

If you don't use PhotoWorks, I don't think you'll have much luck with glowing parts.

I've got an animation running right now, but hope to look up the name of the characteristics I'm thinking of and post back later.
Indirect or global lighting will allow these effects--without them, you won't get good results.

1) Use a fog light which is positioned on the opposite side of the object and shine it towards the viewer. Set object material to transparent plastic. You may need to create a physical barrier so that the fog light is allowed to only shine through the "neon" object. Apply the neon color to the fog light. You do not need indirect illumination to get this effect.
2) Render without the glow and use Photoshop to apply an outer glow to the selected area.
RE: Glowing parts?
What I was thinking of goes back to the PW 1 engine--I cannot find the setting in PW 2. The term was called Emission--as in light emission. I don't see it anywhere.
I used it once to simulate the beam of a laser pointer--transparent part that emitted red light, so it rendered differently than the other parts.
So what Stoker says above should work fine, but it comes with the limits expressed as well. I'll see if I can find another decent substitute.

You'll need to have a darker background/lighting/scene with indirect lighting used.
I'll post some images soon so you can see what this does. It may be what you're looking for.

I modeled two spheres on a blank white base (for reflection and shadows). The first sphere was blue glass (control sphere). The second sphere was altered to see progressive differences in materials, but started as simple Injected Plastic with a typical glow-in-the-dark greenish color.
The first experiment used a material set to Conductor on the second sphere:

The next used a Dielectric, but that still wasn't quite right:

Next, I tried a Constant material, with Transparency:

That was too transparent. Reduced:

Too solid. This seemed better, at .30:

Finally, with a black background and reduced direct lighting:

RE: Glowing parts?
Inerestingly, I use the Constant setting to render logos and such in pure color within SolidWorks. I often find it simpler to generate graphics by creating something in SolidWorks, setting the colors the way they need to be for each element, and then rendering to a TIFF file for use in Photoshop or the decal editor in Photoworks. So I don't normally use it with indirect lighting or transparent parts. It seemed to work well.
This technique ought to work with other types of materials--I chose Injected Plastic since I work with that material type all the time. You can probably choose other materials that better represent the right level of gloss and roughness to get exactly what you need with this method.

RE: Glowing parts?
If you look at the indirect illumination examples, notice that you only see a "glow" on the materials that are adjacent to the neon part. You do not get any glow in the air space surrounding the part. If you look at Jeff's final rendering, there is only glow on the floor next to the bottom surface of the sphere. There is no glow coming from the upper half of the sphere because there is no material next to it to catch the bounced light from the indirect illumination.
The fog light method will give a glow even around areas that are not adjacent to another part. You will get a glow around the entire perimeter.
RE: Glowing parts?
I also think a darker color for the glow-in-the-dark material will offer differing effects--probably to visually-cue the thickness of the material (if it has variable thickness or ribs) because of the material transparency setting. So the effect should be able to be fine-tuned for great results.
