      bladeWaveScale = 1.0,
      bladeWidth = 0.32,
      bladeHeight = 4.0,
      bladeAngle = 1.57,

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.

• The distribution map is an intermediary file compiled into the SMF/SMT files using MapConv or MapConvNG.
• 8 bpp RGB

Spring Map Size*	pixels = Spring Map Size * 64
2	128
4	256
6	284
...	...
32	2048
* must be multiples of 2

Shading Image

• File location: ./maps
• 8 bpp RGB, any resolution, will be stretched over the whole terrain
• If a shading image is not present, the minimap will be used in its place.
