Grass

Grass is entirely optional, but can be customized via map parameters and adds a nice touch to your map.

Specification

mapinfo.lua

local mapinfo = {
   ...
   resources = {
      ...
      grassBladeTex = "",
      grassShadingTex = "",
      ...
   },
   ...
   grass = {
      bladeWaveScale = 1.0,
      bladeWidth = 0.32,
      bladeHeight = 4.0,
      bladeAngle = 1.57,
      bladeColor = {0.59, 0.81, 0.57},
   },
   ...
}

Blade Wave Scale

Defaults to 1. It specifies how much the blades will wave in the wind. Higher makes them wave more.

Blade Color

does nothing when blade texture is set.

Distribution Image

Formerly Feature Map. Grass distribution is defined by blue pixels, the more blue the pixel is (the closer to blue 255 it is), the thicker grass will be at that location.

File Location	The distribution map 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 * 64 2 128 4 256 6 284 ... ... 32 2048 * must be multiples of 2

Shading Image

• If a shading image is not present, the minimap will be used in its place.

File Location	./maps/
File Format	PNG, TGA
Colour Depth	8bpp
Channels	RGB
Resolution	Any, recommended powers of two, will be stretched over the terrain.
