If you notice, my light source is quite dark. In another section where there is no roof, I just added a few extra spot lights to light up my light. In this room I can't. Does anyone have a simple way to make my bulb shine? without adding a spot of light on the roof?

Edit to add:
When I relighted the scene, I placed my spotlights over part of my lights and got a reasonable facimile of light. Smile

my window came out black instead of clear, but I'll get that figured out. (I hope)

Nice workaround!

The simple way you were looking for is to mark the material used for your lightbulb to be 'not affected by the lightmapping process', so you can just use a nice shiny texture for it and have it show up. Unfortunately, that is not yet supported by DeleD Smile

We have had this functionality on the list for quite a while now, but as it requires a change of the file format it has been put on hold. However, 1.4 is a good candidate for foresaid file format change, and it is coming closer every day Very Happy

Thanks. That sounds great.

I thought he meant a self-illuminated material. It would be cool to have a white texture (or any color we require for lights) and being able to se it to be 100% self-illuminated; then we would just apply it to our bulb model or fluorescent light model (cylinder) and place some lights besides it to get the desired effect.

Adobe Atmosphere used textures as lights. It was a great way to place a light. You could make a light object using a cylendar and a cone. Put whatever texture on the cylendar and cone, then use a seperate texture on the round side of the cone that pointed where you wanted light. Set that texture to emit light. Then the light was actually comming from your light.
Personally, the way DeleD does light is fine with me. If I can add a color or glossy texture to my light object so that it looks like it's where the light is comming from, that's fine.

Can I have a cone tho Please?? (that's a triangle with a round end. the one we have is triangle shaped.)

I like the sound of that, Trucker! Smile And as PJ said, we need a fileformat change for functionality like this. We'll try to implement this in 1.4.

I don't really understand what you mean with a triangular cone... do you mean the pyramid? If you want a cone, you could draw a cylinder and weld its top vertices together. Adding a cone primitive is a nice idea though, I think we already got that one on our (200+) TODO list. Wink

That would make my workflo more realistic. Smile
Yes, I was talking about the pyramid.
Duhh, didn't think to weld the tops of a cylendar together. I just made do with squashing a sphere. Embarassed
