Alright, so I was using a Perlin noise terrain script which I got off of the devforum, but for some reason it generates blank areas with no terrain, along the inner corner of an "L" shaped generation. It doesn't clear up whenever you get near, and I haven't been able to figure out what's wrong. Is it something wrong with my settings or the script itself?


local Players = game:GetService("Players")

------------------------------------------------------------------------------------------------------------------------------------------------

local BASE_HEIGHT 		= 10				-- The main height factor for the terrain.
local CHUNK_SCALE 		= 3				-- The grid scale for terrain generation. Should be kept relatively low if used in real-time.
local RENDER_DISTANCE 	= 500 / 4			-- The length/width of chunks in voxels that should be around the player at all times
local X_SCALE 			= 150 / 4		-- How much we should strech the X scale of the generation noise
local Z_SCALE 			= 150 / 4			-- How much we should strech the Z scale of the generation noise
local GENERATION_SEED	= math.random() 	-- Seed for determining the main height map of the terrain.

------------------------------------------------------------------------------------------------------------------------------------------------

local chunks = {}

local function mountLayer(x, heightY, z, material)
	local genstruc = math.random(1,100000)
	local beginY = -BASE_HEIGHT
	local endY = heightY
	
	local cframe = CFrame.new(x * 4 + 2, (beginY + endY) * 4 / 2, z * 4 + 2)
	local size = Vector3.new(4, (endY - beginY) * 4, 4)
	
	workspace.Terrain:FillBlock(cframe,size,material)
end

local function chunkExists(chunkX, chunkZ)
	if not chunks[chunkX] then
		chunks[chunkX] = {}
	end
	return chunks[chunkX][chunkZ]
end



function makeChunk(chunkX, chunkZ)
	local rootPosition = Vector3.new(chunkX * CHUNK_SCALE, 0, chunkZ * CHUNK_SCALE)
	chunks[chunkX][chunkZ] = true -- Acknowledge the chunk's existance.
	for x = 0, CHUNK_SCALE - 1 do
		for z = 0, CHUNK_SCALE - 1 do
			local cx = (chunkX * CHUNK_SCALE) + x
			local cz = (chunkZ * CHUNK_SCALE) + z
			local noise = math.noise(GENERATION_SEED, cx / X_SCALE, cz / Z_SCALE)
			local cy = noise * BASE_HEIGHT
			mountLayer(cx, cy, cz, Enum.Material.Ice)
		end
	end
end

function checkSurroundings(location)
	local chunkX, chunkZ = math.floor(location.X / 3 / CHUNK_SCALE), math.floor(location.Z / 3 / CHUNK_SCALE)
	local range = math.max(1, RENDER_DISTANCE / CHUNK_SCALE)
	for x = -range, range do
		for z = -range, range do
			local cx, cz = chunkX + x
			local cz = chunkZ + z
			if not chunkExists(cx, cz) then
				makeChunk(cx, cz)
			end
		end
	end
end

while true do
	for _, player in pairs(Players:GetPlayers()) do
		if player.Character then
			local humanoidRootPart = player.Character:FindFirstChild("HumanoidRootPart")
			if humanoidRootPart then
				checkSurroundings(humanoidRootPart.Position)
			end
		end
	end
	wait(1)
end

I've tried changing render distance and chunk scale, but I don't really understand most of the math in the generation or how it's scripted. Somewhat of a noob to scripting, but trying to figure things out. Is this generator flawed? and if so, where can I find and or script a better one? Thanks.
