I'm going to be asking a lot of questions, and each person who answers my questions gets a +rep/thanks from me. Here is a question: I've got this (terrible-looking, to be changed, tips on textures for the red and blue sections which will have glass between them) start of a trade map here: I want to put a "disco" light that changes colour. I'm very new with lights. How do I make a spotlight which has a visible "beam" (not a laser beam, but as if it is showing up dust) and changes colour? Thanks. Also, what is "falloff"?
