Nathaniel Doldersum – MCS Caves Overhangs v1.27

The easiest way to create caves and overhangs (and best looking) is by stacking your rock models inside the Unity Editor. The issues:
1). It’s bad for performance because there’s a lot of rock geometry (triangles) that overlaps with other rocks or are below the terrain. So many triangles are drawn that are never visible and this also results in overdraw on the GPU which reduces performance.
2). It’s bad for lightmapping. Lightmapping gives the best looking results especially on caves but a lot of lightmap texture space (increase in memory needed) is wasted with the never visible rock triangles.
