Is there any source on BGT chapter numbering? For example, if I want to say "after Underdark" in BGT environment, which value in GlobalGT("Chapter","GLOBAL",???) I should use?
Edit: actually now that I have thought about it: does BGT changes chapter numbering in BG2 at all, or it just builds up chapter number during BG1, then resets it, and builds up again from chapter 1 in BG2?
Here is my own homemade one I used developping my mod - hope the description make some sense to you (Disregard the last numbers, they are for EET which finally has a continuous numbering, hallelujah)
BG1
Chapter 1, escaping from Candlekeep. >>0
Chapter 2, outside but not yet in Naskel. >>1
Chapter 3, after going to Naskel, but before looting the chest in the Naskel Mines. >>2
Chapter 4, after that and before looting the Bandit Camps chest. >>3
Chapter 5, killing Davaeorn in the Cloakwood Mines should start the next chapter. >>4
Chapter 6, getting to talking to the grand Duke Elthan and taking to book. >>5
Chapter 7, after facing Sarevok first time. >>6
Chapter 8, the chapter changes after talking to Belt the last time >>7
8-14 Dragonspear
