Issues with a terrain generation system that uses Hexagons

[hazame4 (Linus_TechTips)]

i honestly have no idea whats wrong there, maybe try halving the Y too?

Does your generations uses Zigzags or Straight offsets in grid?
This depends how you need structure placement.

[Carter_ST1]

I think it uses zigzag offsets.

If I half the Y value, then it would be z-clipping the tiles underneath it.

Can you show me function which places hexagons? (Part which calculates Vector3/CFrame where they should be placed, not just Hexagon.CFrame = smth)

[Carter_ST1]

It is just a for loop:

(mapsize = 16; yMin = 1; yMax = 16)

for x = 1, mapSize do
		for y = yMin, yMax do
			for z = 1, mapSize do
				local d = mapGet(densityMap, x*offset["x"], y, z*offset["z"]) 
				--print(d, x*offset["x"], y, z*offset["z"])

				if d >= 0 and d <= 0.14 then
					local block = workspace.blockBase.Base_Plane:Clone()
					--local block = Instance.new("Part", workspace)
					--block.Size = Vector3.new(4, 4, 4)
					
					z *= 3.732 * 0.5

					block.Anchored = true
					block.CFrame = CFrame.new((x*offset["x"])*4, y*4, (z*offset["z"])*3.732) -- this is the positioning
					block.Color = Color3.fromHSV(((y/mapSize)%1), .75, 1 - (y/mapSize))
					block.Parent = game.Workspace
				end

			end

		end
		game["Run Service"].Heartbeat:Wait()
	end

Try to construct CFrame for hexagons using this base:
CFrame.new(0.866*(x - z%2/2), 0, z*0.75)
Idk what your offset.x mean, and why you multiply them by 4, 3.732, maybe they should be inserted like this:
(Note: dictionary[“Name”] == dictionary.Name, if Nameis string. Otherwise, use like you did, with [])
CFrame.new(0.866*(x*offset.x - z%2/2), 0, z*offset.z*0.75)
I wrote this base for tiles with hexagon diameter 1.

[Carter_ST1]

This works, but can you give me a base for a hexagon the size of 4?

[GamEditoPro]

Multiply X and Z values by 4
CFrame.new(3.464*(x - z%2/2), 0, z*3)

[Carter_ST1]

I have an issue: the following image shows a little offset issue that I can’t figure out. What do you suggest?

[GamEditoPro]

1st - your hexagons are not ideal =[
Ideal hexagon should have following size: (0.866, Y, 1)*N. (or swap X and Z if it still squashed)
My formula was for perfect hexagons.
Second - your hexagons have swapped X/Z axis, so swap positioning too.
CFrame.new(z*3, 0, 3.464*(x - z%2/2))

Thank you very much! That fixed it!
