Output Generators bring all the map and object inputs to life: convert maps to terrain heightmap, splatmap or detailmap and place real objects on terrain. All of the generator chains should end up in one (or more) Output Generators - otherwise they will not be generated at all.
Input: a map that will be applied to terrain.
A scale parameter resizes the final heightmap before applicationapply: when set to 0.5 the terrain heightmap resolution will be the half of the map resolution that is set in Settings. When the parameter is equal to 2 it will upscale the map twice with bilinear filtering.
