TC2M Mod - The Making of Bath: Part 3

With the topography set, the terrain features are added with a tga file. Gray scale values on the tga file correspond to a spreadsheet that associates the gray scale value with terrain features likes trees, rocks and grass. It also associates each gray scale value with movement rates, fatigue penalties and defensive bonuses. This is what allows troops to move faster on the road without fatigue, but slower and with added fatigue through creeks, woods or other difficult terrain.

I have also started painting the terrain features on a file that is laid over top of the topography to show where the roads are and give other ground colors or textures.

The tga file: The large dark areas are woods. The dark gray areas are also woods, but with pine trees. Roads and streams are visible. I have not added fields and farms yet. 

The terrain file. This is what give the textures and colors on the ground.
