BeefBacon's Terrain and Landscaping Pack addon - Mount & Blade: Warband

While this pack was originally intended for use in mods such as Persistent Kingdoms, it can be used for scenes in any mod.

Models are all low-poly, and use vanilla textures. This means that they should remain visually consistent even if your mod uses custom terrain textures.

Many models have texture variants applicable to different types of terrain (grass, snow and so on).

Not included are the changes you'll need to make to scene_props. You'll need to add meshes and their collision meshes (all located in terrain_collision.brf) manually.
