ROTTERdam: Road Texture Terrain Edge Remover

Hides the ugly black shadows that appear on roads when placed too close at different heights. Because I can't fix the shader itself, this works by making the road believe the terrain underneath was flat. This works by providing it with a manipulated surface normal map that points upwards everywhere.

• overwrite terrain appearance (default off) (used to be called "hide cliff texture")
  
  with this setting enabled, the terrain mesh will use the manipulated surface normal map as well. This means that it won't display the cliff texture and will be shaded as if it was flat.
  This has the advantage of lower RAM usage, as no additional textures need to be created.
  
  
• operating mode
  
  
  • erase mode (default): all normals are set to vertical. The strength setting is ignored.
    Fastest, but has some side effects (see below)
    
  • clamp mode: normals are limited to a set range around vertical. Values within that range are unaffected, values outside are moved to the boundary.
    
  • scale mode: normals are scaled to a set range around vertical.
    
  
  
• strength
  
  defines the range used by clamp and scale mode. A strength of 0 means all values are allowed (thus no effect), a strength of 128 means only vertical is allowed (result equal to erase mode).

• nature reserve paths and similar don't blend in when placed on sloped terrain.
  This can be fixed by using Clamp mode with a strength around 100 (recommended) or by enabling the "overwrite terrain appearance" option.
  
  
• With the "overwrite terrain appearance" option enabled, the topographic lines overlay is broken. Either disable that option, or use clamp mode with a strength of 120 or lower, or scale mode with a strength of 100 or lower.
  
  
• networks will always display the grass, never the cliff texture. This is especially noticeable with e.g. D͓̽X͓̽'s slope profiles.
