Question how to demonstrate the serchlight effect

[weiqi]

I have created a launch base ,and there are some searchlight in the base. When the night comes, I want to open the searchligh ,but I don't kown how to demonstrate the serchlight effect. In addition, if I want to make the light beam turns around with the serchlight, what should I do?

Thanks a lot for your help!

I have not done it before, but I suggest that the effect could be achieved by using an exhaust texture.

I once tried that and posted at Dan's Forum about it (not very interesting) but it's impossible yet (unless you know some way to change specific parts of textures temporally). If you use exhausts it may look like the lights, but it won't lit up the ground or other spacecraft.
To see in the dark use [ame="http://www.orbithangar.com/searchid.php?ID=2645"]Camera MFD[/ame] as it has got a Night Vision mode.
