This tutorial explains how to add additional land masses to the map. Before reading this tutorial I recommend reading my how to split a region tutorial because it I will not be covering anything that's explained in this tutorial:

Tweak New Sea
Spoiler Alert, click show to read:1) Open the DB table regions_sea.
- Click the "Add record" button to add a new row.
- Copy and paste an existing record into the new record which is the same type as your new sea region.
- Give this sea a unique ID, such as "jap_bohai_sea".
- Give this sea a name, such as "Bohai Sea".
When finished click the Apply button.
3D Max Part 1, new land mass
Spoiler Alert, click show to read:1) Using 3D max open the "total war shogun 2\modding\raw_data\EmpireDesignData\campaign_maps\sho_japan\Shogun2.max".
2) Select the modify tab and use the "cut" tool to create a new land mass.
Before:
After:
3) Using my "How to split a region" guide add a new region to this land mass.

Make sure that at the edge of the map is a sea or no_go land region. If a land region touches the edge of the map this will prevent the pathfinding being created on all the land regions in this new land mass, which will prevent any units being able to walk on it.
4) Hide all layers except the Regions.cs2.
5) Hold down the <Ctrl> key and press the <A> key to select everything.
6) Press the 3DS button and in the pop-up menu select "Export", then select "Export selected". Export this file as the Regions.CS2 in the campaign_map folder you're editing.
3D Max Part 2, new mountains
Spoiler Alert, click show to read:1) Unhide and freeze the Regions.cs2 layer. This will prevent you accidentally selecting it.
2) Unhide the "Mountains.cs2" layer.
3) In the Create menu use the line tool to create a spline (a curve connected by two or more points) where the mountain is located.
4) When asked if you want to "Close spline?" click Yes.
5) Give this mountain a unique name. In this example I use "Mountain84".
6) Repeat for all other mountains you want to add.
7) Hide all layers except the "Mountains.cs2".
8) Press the 3DS button and in the pop-up menu select "Export", then select "Export selected". Export this file as the Mountains.CS2 in the campaign_map folder you're editing.
3D Max Part 3, new sea region
Spoiler Alert, click show to read:1) Hide all layers except the Regions.cs2 layer.
2) Press <M> to bring up the Material editor.
3) Click the "Add" button. This will create a new material at the bottom of this list.
4) Give this region a unique ID and Name. In this example I used 415 and Bohai Sea.
5) Click on the button in the "Sub-Material" column to bring up the sub-material menu.
6) In this menu rename the material. The name of this material has to contain the "sea_" prefix and the name of the sea from the "regions_sea" DB Table. In this example it's sea_jap_bohai_sea.
Then click the grey box next to "Diffuse" and in the pop-up menu choose the colour you assigned to this region using Tweak. In this example it's R:180, G:180, B:180.
7) Select the modify tab and use the "cut" tool on the area you wish to split into two sea regions. In this example I split the Yellow Sea area.
8) Set the selection tool to "Polygon". Hold down <ctrl> and select all the polygons in your new region. In the image the selected polygons are all red.
9) In the "Polygon:Material IDs" "Set ID:" box enter the ID of your new region (210 in this example). This will assign these polygons to your new region. If done correctly these polygons will change to the colour of your new sea region.
10) Hide all layers except the Regions.cs2.
11) Hold down the <Ctrl> key and press the <A> key to select everything.
12) Press the 3DS button and in the pop-up menu select "Export", then select "Export selected". Export this file as the Regions.CS2 in the campaign_map folder you're editing.
3D Max Part 4, new sea ground type
Spoiler Alert, click show to read:1) Unhide and freeze the Regions.cs2 layer. This will prevent you accidentally selecting it.
2) Unhide the "Sea_ground_types.cs2" layer. The dark areas are where sea attrition occurs, the light areas don't cause sea attrition.
3) Select the modify tab and use the "cut" tool on the area you want ships to be able to safely sail.
8) Set the selection tool to "Polygon". Hold down <ctrl> and select all the polygons in your new region. In the image the selected polygons are all red.
9) In the "Polygon:Material IDs" "Set ID:" box enter the ID of your new region (9 in this example). This will assign these polygons to your new region. If done correctly these polygons will become transparent.
10) Hide all layers except the Sea_ground_types.cs2.
11) Hold down the <Ctrl> key and press the <A> key to select everything.
12) Press the 3DS button and in the pop-up menu select "Export", then select "Export selected". Export this file as the Sea_ground_types.CS2 in the campaign_map folder you're editing.
