Bob is in two parts because if you try to make the startpos.esf without using a mod pack containing the regions.esf and pathfinding.esf you made in
Bob Part 1 then TWS2 will use the vanilla versions of these files instead. As the vanilla versions don't contain your changes the startpos.esf also won't contain your changes.
1) In the "Raw Data" menu go to the "EmpireDesignData/campaign" folder and check the "jap_shogun" box. On the pop-up menu select "all". Then press the "start" button to build the startpos.esf.
2) In order to create the startpos.esf BOB needs to start TWS2; so when prompted start TWS2. If you have the Steam version then you also need to have Steam running before you start TWS2.
When asked if you want to load a mod pack select the mod pack you made in
Bob Part 1 that contains the pathfinding.esf and regions.esf you made. If you don' use a mod pack then TWS2 will use the vanilla versions of these files and produce a startpos.esf that won't work.
3) Don't worry about any orange error messages. However the red messages mean that you've made a mistake in one of the files, so you need to edit the files it mentions.
4) One BOB has finished you need to add the new startpos.esf from the "total war shogun 2\modding\working_data
" folder to a mod pack using the Pack File Manager (PFM). The startpos.esf has to go in the
campaigns\jap_shogun folder.
