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.
