Fixing Editable Mesh UV Calculation

  1. What do you want to achieve?
    I am trying to tile a texture over an editable mesh grid using GetUVs and SetUV.

  2. What is the issue?
    The texture tiles correctly over certain sections of the mesh, but is stretched weirdly in several rows/columns.

  3. What solutions have you tried so far?
    I have tried debugging with print statements but could not find anything that points to why this could be happening. I do not fully understand how UVs work on editable meshes and there is not much documentation regarding UVs so I am most likely doing something wrong. Should I be setting the UV position to something other than Vector2.new(x, y)?

Here is my code for updating the UVs:

local vertices = {} -- 2D array: vertices[x][y] = vertex_id

RunService.Heartbeat:Connect(function(dt)
	local uvs = TestOceanMesh:GetUVs()
	local k = 1

	for x, _y in vertices do
		for y, vertexId in _y do
			TestOceanMesh:SetUV(uvs[k], Vector2.new(x, y))
			k += 1
		end
	end

end)

NOTE: The vertices 2D array holds 400 vertices ranging from x=1, y=1 to x=20, y=20.

Here is an image of what is happening (the texture is displayed on the left):
