Lighting questions

[LexiMax]

With as much mapping as I have done, I'm still unclear on how synced lighting works. Sometimes, if I have two sectors adjascent to each other, they seem to sync with each other. Other times, they don't, and I end up with a mess. How can I ensure that sector effects, such as blibnking and flickering, is synced?

Flickering won't synch no matter what you do. Blinking can, however. There are two options: Light Blinks 0.5 sec synch (sector special 12) or Light Blinks 1 sec synch (sector special 13).
