You have to play around with the scene ambient color and the material ambient color in the material editor. Other than that, I'm not firm enough there to write a tutorial about that, I'm afraid!

I'm guessing you're refering to the Raytracer?

Quick hints: set the Intensity to a value greater than 100. Like, 500 for example. Also set the Range to a higher value. Your point lights should not be too far away from the object because they won't affect the object if they are.

More info about the raytracer will be made available a.s.a.p.

You have to tell us what you're trying to do.

If you create a pointlight just outside the window, have its intensity set to 500 and range to 2000, things should work. At least, that's what I just did to test it. Smile

Do you mean that the light shines through a transparent surface? That sounds pretty advanced to me (programming point-of-view) Shocked

Does indeed look like you are trying to render light falling through a transparent surface. Here are some remarks to help you going
a) The raytracer doesn't support alpha in texturing yet (that's more of a realtime 3D thing, the raytracer is foremost material based, not texture based). To create transparent surfaces, use the Transparency slider in the lower right of the material editor. Easy on the refraction, unless you want the light to do unexpect things. (*)
b) Raytracer transparency works nothing like the current lightmapper implementation, it's a bit more realistic and a lot more complex. Just saying, don't expect wysiwig translations of lighting to the raytracer.
c) The current raytracer implementation is a bit rough around the edges, so even if you've taken (a) and (b) into account, you might have stumbled upon a silly bug. I'll investigate.

(*) Yes this should have been documented in the Wiki. Working on it. If anyone wants to contribute, they are more then welcome.
