The first Mod was not set up to work with JSGME , so if you set it up to work with that program I would uninstall Ver 1.0. Ver 2.0 is a complete set minus 1 guy which I did not do for symbolic reasons and is set up for JSGME.
2.0 looks better IMO,, I made some filters and ran all the units through them to enhance. I have no plans for a Ver 3.0 unless I find some problems or the Models get a update.
Also on a small note there are some minor errors I notice with the assignment of Units. I will point out just a few that stood out.
1 The Denmark General L040.dds is using the wrong 3D figure, Index 0C0 type 25 should be the type assigned.
2. The Prussian General 4040.dds is not set up as the General, instead the dragoon Officer 4140.dds is being used.
3. Russian, Sweden, Wurtemberg, Sax, Bavaria have limber units for both foot and horse but only one is used.
Also while you can not add units to the database (at least I have not found out how to yet), you can alter the 3D figure and graphic number it is using. Example all the Units for Saxons currently use a 1812 style uniform look. However you can Mod this and give them 1805 look with bicorn hats.
As far as Modding the terrain, I will wait till it gets undated before I jump back into that area.
