Re: LED-lighting Andrey, The current light bulbs are "proportion fixed", meaning they are always perfect spheres. The old light bulbs, however, could be stretched in any dimension. I think you can download them from this link. I tried using these old lights, but didn't get perfect results either: the light is concentrated in the centre of the elongated light bulb, because light is defined as originating from one central point. But, you may want to experiment for yourself. You can distinguish the old lights from the new lights: the new lights have as part of their name the words "created by eTeks". If these aren't the correct lights, try searching for BasicPlusExtraLights.sh3f, ExtraLights.sh3f or somethingLights.sh3f. In general: - Small lights give sharp shadows, large lights give soft shadows, so you may want to try very large lights. - Light doesn't bounce or reflect as it would in real life; this speeds up rendering a lot, but the drawback is that light doesn't disperse as well as in real life. I think there is a way to set this reflection value higher by changing the source code of SH3D, but I couldn't find that message. - I tried replacing the light bulbs in my example with a VERY long fluorescent strip, but the light is concentrated in the centre of the strip, regardless how long you make it.
