-- Infinite Smooth Canyon Generator :3
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-- CONFIGURATION:
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
 
baseHeight = 10
-- ^ The main height factor for the terrain.
 
mountainHeight = 5
-- ^ How tall should mountains be relative to the baseHeight of the terrain
 
mountainMaterialWeight = 0
-- ^ The chance that a mountain terrain chunk will generate using slate rather than rock
--    Should be a number between 0 and 1
--    0 = only rock, 1 = only slate, 0.5 = half n half
canyonMaterialDensity = 0
-- ^ The limestone rarity
-- 0 = No Limestone at all , 1 = Only limestone (NOT RECOMMANDED) , 0.2 = small bumps (Realist)
-- Note that limestone is not very different from sand, but it adds some realism
chunkScale = 2
-- ^ The grid scale for terrain generation.
 
renderDist = 50
-- ^ The length/width of chunks in voxels that should be around the player at all times
 
xScale = 10
-- ^ How much we should strech the X scale of the generation noise
 
zScale = 20
-- ^ How much we should strech the Z scale of the generation noise
 
waterLevel = 0
-- ^ Determines if we should generate ponds if the height level goes below this
--    Should be a number between -1 and 1
--    -1 = no water, 0 = all grass levels are filled with water, 1 = The entire map is flooded with water (Except for tall mountains)
 
seed = math.random()
-- ^ Seed for determining the height map of the terrain.
--    By default its random.
