Lots of users have been asking for help with using the terrain packs for their first person/third person games. I’ve just updated the Rocky Hills Terrain Pack with custom splatmaps, seamless textures, a ReplaceSplatMap editorscript, and a new demo scene showing off what’s possible.
The custom splatmaps are derived from the topography of the underlying terrain. You get rocks on sheer faces. Dirt on the erosion paths. A set of tiling textures for use on the Unity Terrains is included.
Be sure to check it out on the Rocky Hills Asset Store page and the Rocky Hills project page.
