A billowy terrain featuring channelled erosion. Two slightly-different textured versions set up as two different scenes.
Original scale: 16 km. x 16 km. Poly count: ~40k
Created with game engine use in mind, but useful for animation and illustration as well. Fairly decent for a game. (Probably should still be reduced to lower poly count.)
I'm using a tiled version of this for a game demo, though not in the final game, so I can share this. This is untiled and without added detail textures such as dirt and grass (I'm using Mayang's textures, so I can't share those detail textures).
With your own added details, you should have a terrain that doesn't look anything close to how my own usage will look--not that I mind. ;)
The maps and masks for your own further texturing:

No credit required. Use it in any project. Go nuts. :)
[Note: Give the SketchFab display a little time to load the textures if it appears black.]
