The height map terrain has some very nice features. It can use splat-mapping for multiple materials on one terrain, and it also uses UVW so that materials can map properly onto vertical surfaces.
I think those same features would be very helpful for much smaller terrains. If we could scale the height map terrain on X and Y to cover a smaller area, and so be a higher density mesh, and have the 4 texture and UVW feature, it would help for creating smaller scenes.
We can certainly use just a portion of it, but the polygon density ends up being to low for road/path edges.
