Summary: This shows you how you can make rivers wide enough to allow ships to travel up them, while still allowing troops to cross them

The rivers in RTW aren't really great, mainly because they aren't compatible with fleets and naval trade.

Hopefully, Duke John found a way to create more realist rivers that can be crossed by armies, and I'll try to explain you how to do so :

First, draw the river on your map_heights.tga and map_ground_types.tga files.

Basically, it should look like that :
Map_heights :


Mag_ground_types :


Once that's done, draw the same river on the map_region.tga, so it looks like this :


Now, you have to add one pixel that will allow any army to cross this river. The crossing should not be longer than one pixel, and your map_regions river must fit perfectly with the map_heights and map_ground_types rivers, or it will not work :


In game screenshots :





As you can see, both armies and fleets may use this kind of river, which is much better than the map_features rivers (and it probably allows naval trade aswell).

I did not know where to put this How to.
Sorry for my bad english
