Diffuse

The colour of the terrain, then modified with the lighting values in mapinfo.lua

Example

Example Diffuse Map	Ingame Result

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,
      ...
   },
   ...
}

Image File

File Location	The diffuse texture is an intermediary file compiled into the SMF/SMT files using MapConv or MapConvNG.
File Format	Any that Mapconv programs support
Colour Depth	8bpp
Channels	RGB
Resolution	Spring Map Size* pixels = Spring Map Size * 512 2 1024 4 2048 6 3072 ... ... 32 16 384 * must be multiples of 2

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.
