OK, I've finally managed to get the PCGen output sheets I've been working on into usable shape. Please post any comments, bugs or requests to this thread.
There are 2 output sheets in the attached ZIP file. One for PCs and one for NPCs (i.e. Personalities).
BIG NOTE: Please be aware that changes to the campaign database could cause your database to be wiped when you load FG2, so always make a copy of your entire campaign folder before you make any manual changes to your campaign database file.
The output from these sheets is XML that can be copied and pasted into the FG2 campaign database file. (located at C:\AppData\Roaming\Fantasy Grounds II\campaigns\<campaign name>\db.xml
You need to make an id entry in the appropriate section for each PC or NPC you are adding. The section tags are charsheet and npc, respectively. If you are having trouble, try making some examples in FG2, so that you can see how one looks when saved by FG2.
If anybody has an import script in the works, let me know and I can help make a PCGen output sheet to match.
