I just finished his cutscene the other day and the rest of it works fine. The problem is that the "CutCreatePCCopy"(created by adding in the '#include "x2_inc_cutscene"' statement) function seems to be making a copy of all the characters in the scene, who just stand there while the PC Copy goes thorough the motions. I tried replacing the PC Copy with the real PC, but it always makes the PC invisible, and I tried removing the effect but it does not work.

From my script:
location LocPCCopy = GetLocation(GetWaypointByTag("WP_PC_COPY"));
object oCopy = CutCreatePCCopy(oPlayer, LocPCCopy, "PreludePCCopy");

(oPlayer is oPC)

From Official HotU Campaign:
location lLoc = GetLocation(GetWaypointByTag("wp_cut20_pccopy_star t"));
object oCopy = CutCreatePCCopy(oPC, lLoc, "PreludePCCopy");

I dont see what I did wrong here, if anyone can enlighten me I would be very grateful :D

I'm not sure what you are asking. You have copied the PC and you say the PC is going through the called commands?
Are you looking to make the original PC invisible? Or are you looking for a way to destroy the copy after the cutscene ends? There are commands for both.

Could you post the function CutCreatePCCopy()?
You can do that by opening the script you include and search for the function.

Perhaps there's something in there that makes it work like this? Sometimes the Bioware functions are made for their specific situation and that's why they don't put it in the scripting functions list.
