What I'm trying to figure out is how to combine scenes with dialog views? For example, start a scene, then halfway through have an NPC forcegreet and go to a dialog view, then return to the scene, have another NPC forcegreet to a different dialog view, etc...
I'm working with this right now. I'm not sure if there's an easier way, but what I did is make several small scenes and tied them together with quest-declared INTs, which determine what is said when. The NPC does his scenes based on both the INTs and his location. I don't use alot forcegreets to continue the action (as I figured too many forcegreets would be annoying), so I'm experimenting with triggerboxes in spots when there is no required input from the Player (just that the PC hear what was said). I'm not sure if that's the way to go yet.
OP: Didn't mean to hijack the thread. Knock on wood, I haven't had any quest-package problems that I couldn't solve. All the troubleshooting I can think of, you've already done. Considering that I floundered through packages like the Sta-Puff marshmallow man through New York, I'm definately no expert. Your problem perplexes me.
