The triggerd light is nice, create a light and when you shoot at it the light goes out. Add a triggered glass shard particle and a triggered 'breaking of glass' sound and that could work out nice in true combat or urban terror.
I have been wondering if it would be possible, after extracting the lightmaps to a directory, to manipulate the lightmaps with a shader file to give a dynamic light effect? Basicly have a black image that useing the 'rgbGen wave noise' over top of a light map would make a light seem to flicker on and off?
I put the new in b.
