Hey guys,
Does anyone know if the performance hit from upping heightmap resolution only applies to visible terrain?
Thanks in advance :)
As far as I know, your height map is never so much as loaded into memory on the player's computer. The height map is just used as a guide as to how to model your terrain, and after the terrain has been modeled, the height map is discarded. You can increase your height map's resolution to an infinite degree but unless you actually increase the density of your terrain's polygons, nothing will change performance-wise.
