Mapdev:diffuse

Diffuse

The colour of the terrain. The diffuse image texture is compiled with mapconv into the SMT/SMF files. In game, the color is then modified with the lighting values in mapinfo.lua

Specification

mapinfo.lua

The relevant sections of the mapinfo.lua file that effect the colour of the ground are in the Lighting subtable

local mapinfo = {
   ...
   lighting = {
      ...
      --// ground lighting
      groundAmbientColor  = {0.5, 0.5, 0.5},
      groundDiffuseColor  = {0.5, 0.5, 0.5},
      groundSpecularColor = {0.1, 0.1, 0.1},
      groundShadowDensity = 0.8,
      ...
   },
   ...
}

Compression

It's possible to reduce the size of the final map by using a repeating pattern in your texture image. mapconv auto detects that pattern and saves each unique tile that you've used as DDS inside the mapfile.
