I don't keep my BG1 items at the beginning of BG2 as it's basically cheat...
If you import a character from BG1 to BGII, it is recognised by the dungeon area script (AR0602.BCS) whether you have some special items on you before all items are taken from the PC (and the Irenicus-Cutscene starts.)
This way BGII knows whether you have the pantaloons from BG1. The script goes:
CODE
IF
Global("BG1Pantaloons","GLOBAL",0)
PartyHasItem("MISC47") // Goldene Pantalons
THEN
RESPONSE #100
SetGlobal("BG1Pantaloons","GLOBAL",1)
ActionOverride("Picture1",CreateItem("MISC47",0,0,0)) // Goldene Pantalons
Continue()
END
so you will find the pantaloons in the dungeon then.
This way it's also triggered whether you had some of Drizzt's items of BG1, which leads to a rather unpleasant greeting from the drow in the BGII-encounter...
Maybe the last that I wrote could be thought of some kind of "easter egg", at least it's one unexpected (because not connected to a joinable NPC) connection between BG1 and BGII.
