Kerkythea & Sketchup - glow?

ok. We're trying to get something to have a slight glow. The model was made in sketchup and is rendered in Kerkythea.
Its obvious that natural glow isn't possible in sketchup alone. which is why we also use Kerkythea

anyone got tips on how to go about it?

The purpose is to make a set of eyes have a slight blue glow to them, yet still have the same base colors as regular eyes.

We've tried adding a little transparency to the eyeball & placing a light source behind it, but all that has done is make a small bright spot on each side of the bridge of the nose.
The thought is to have a small rather slight bluish glowing area around the eye so it seems to glow. Not enough to obstruct eye color, but enough to be noticeable.

anyone got a solution?

    Kerkythea has light emitting/self illuminating materials, you could use those on the iris. Unless you make it very strong though, the light would only be obvious when there is not much light hitting the eye.

    Ahh... then we'll just have to figure out how to use those then...

    While we never got the glowing eyes thingy to work, we have figured out how to get glow out of things like engines and lanterns. Even colored lights.

    When we made those things, we put a light source in the middle of a solid shape with a semi-transparent color. To get it to work, one should not make that solid shape a separate group, as that causes light to go white.

    we figured that writing such down here might help others that have such problems in the future.

    EDIT: It has turned out in hindsight that making colored lights is much, much easier... All one has to do is paint the lightsource the color one wants. Not sure if it affects the light what material or transparency the lightsource has, but at least the color value affects the resultant color.

    Open up the material editor in Kerkythea. Any material used will have a box for self-illumination. You can use simple colors or bitmaps, and you can adjust the intensity to what ever your needs are. Keep in mind that self-illuminated materials substantially increase render time.

    the problem we still have is that there's so many interesting things to change that it is easy to get lost...

    The essence of the issue with that model we asked this question for is "how to get it to glow faintly blue, yet not recolor the whites of the eyes?"

    We've not tested much on that front since the model was deemed "finished", but we'll certainly keep it in mind in the future for newer models...

    The render time on that specific model was surprisingly short considering the fact that it had nearly 150k faces. So added render time is no problem.

    We'll take a look at fixing that part when we become better at using kerkythea. Thanks for the tip though, Sorceress21...
