Well I've been working on a church scene that I've been asking various tips for, and I'm up to the final stage for me, which is lighting. I've got the majority of the lighting done, but theres one thing I've yet to get working.

Basically, within my church's walls I have cut windows shapes along the side, and inserted planes within these holes, and I would like the planes to have a yellow-orange glow as to give the effect that there is firelight behind the window.

Is there a good way to apply a kind of glow to an object, whilst maintaining its texture? (In this case, a stained glass effect)

I have tried checking the Self-Illumination checkbox under Blin Basic Parameters of my window texture, but the best I've been able to do is set this to the colour I want - which simply makes the window a bright orange, but doesnt really give a glow as such.

Find a nice stained glass window texture and use that in the self illumination channel aswell as diffuse. go a step further and edit the texture for the self illumination paint black everywhere that isnt transparent use the original in the diffuse.

OK I tried this, but although it did brighten up the window giving it a better effect, I still havent managed to quite get the glow I'm looking for.

I'm not sure what the exact term is, but I'm looking to make an effect where there is a bit of light falloff coming from the window.. sort of like the glow of a volume light. That kind of blurry glow that comes from the light inside the window illuminating the near vicinity of the window outside. I can live without it, if its complicated, but since its my dissertation I'd like to try.

Edit: This is sort of what I'm imagining, but just in the vicinity close to the window itself

I did see someone who'd done it on here before, but I cant seem to find that topic now.

Getting the volume light effect would probably require modelling the window and using a spotlight from inside or maybe doing a special pass its a bit of a tricky setup. If you use an omni just outside the window with attenuation on then do a bit of photoshop work to it such as screening a blurred version of the image over the top you should be able to get a pretty nice effect.

Thanks Tyson, I'll have a play around with it but if I cant get it working I'll have to leave it, got some write up left to do yet and my deadlines extremely close confused.gif

If this proves too difficult or time consuming you could try a simple glow effect and select the window as the glow object. It wouldn't look as good as the volume light but it might be ok for what you want.
