Hi GT.
I was wondering how I could add a spotlight to my model. By spotlight, I was talking about something like you see on the street lamps in Jinglin' Town. I tried adding a spotlight by going to Get > Primitive > Light > Spot, but it didn't look as it does in Jinglin' Town, so I assumed I was doing something wrong. Also, the idea was so that the other parts of the model are hard to see due to shadow (kin of like the tops of the _world mesh parts in the Mustafar assets). Could someone please help me out?
Thanks.

You can use a real light (a light .odf based off of a null) - see stock models for further elaboration. You can also use a semitransparent mesh as the "cone" of the light, but that doesn't add any lighting by itself.

Ah, great. Thanks, Mav'!
