positive.code: .  Specify a name: E.g. `my terrain`.
  .  Specify tile size: You want to terrain tiles of size 64x64, so you supply 64+1 = 65.
  **  In general, 64 is a good starting value for terrain tiles.
  
  .  Specify block size: Since you prepared a heightmap of size 512x512, you supply 512+1 = 513.
  **  If you supply a block size of 2x the heightmap size (1024+1=1025), you get a stretched out, wider, flatter terrain.
  **  If you supply a block size 1/2 the heightmap size (256+1=257), you get a smaller, more detailed terrain.
  
  .  Supply the 512x512 heightmap object that you created.

  The individual texture scales (e.g. `mat_terrain.setFloat("Tex3Scale", 128f);`) depend on the size of the textures you use.
  
  *  You can tell you picked too small a scale if, for example, your road tiles appear like tiny grains of sand. 
  *  You can tell you picked too big a scale if, for example, the blades of grass look like twigs.
