no blue hints?
Oooppsss.... sorry, forgot to say that;
I have no real idea, other than to say that some of the door activation bit is hard coded into the game. I vaguely remember requesting a change on that from BIoware, back during WCoC dev days when we still had Bioware's ear. There was a HUGE list of requested changes that folks wanted though, and as well all know, only so many were addressed.
Been a while, but I think even a hidden door will still give a blue rectangle when you pass your mouse over it? Will show up when you hit tab in game etc? As I said, it has been a LONG time since I even considered making door changes other than tileset specific ones, and even then there is a limit to how many you can assign per tileset I believe, but I am likely wrong on that, someone else would have to clarify it for us.
If anyone still has any contact information for OldMansBeard, he would be the wizard with the answers. Although, I do believe that he has put NWN on far back burner, likely turned off completely, since he is working with Skyrim development now, doing scripting again, which is his strong suit and most enjoyable for him I believe.
You might possibly be able to get the NWNX folks to take a look at possible solutions for the blue highlighting though. Bioware just didn't have the resources assigned to NWN long before 1.69, we had to beg, borrow and steal folks to get 1.69 out the door as it was. Of course, BIoware DID come through for us with 1.69, and we all should honestly thank them for their very major efforts for a game that they no longer recieved any compensation for, regardless of sales.
