This snippet allow to make simmetry, or some rescale operations inside tiles, but saves ability to decrease "Size, Pixels" and apply randomization advantagies. Unfortunately this technique stop work with forces seamless tiling

In general: basic graient + (image bounds free gradient * SIZE)

Code

function prepare()
   -- This function is called once,
   -- before the rendering begins.
   -- Use it for querying non-mapped
   -- inputs and precalculation.
   is_X = get_checkbox_input(X_OR_Y)
   max = SIZE
   if (is_X) then
      max = max * SEAMLESS_REGION_WIDTH
   else
      max = max * SEAMLESS_REGION_HEIGHT
   end;
end;

function get_sample(x, y)
   -- Image generation code goes here.
   local remapGradient = get_sample_grayscale(x, y, GRADIENT)

   if is_X then
      x = round(x)
   else
      y = round(y)
   end;
   local globalV = get_sample_grayscale(x, y, IMAGEGRADIENT) * max
   local result = remapGradient + globalV
   return result, result, result, 1
end;

function round(num)
   return math.floor(num)
   --local mult = 10^(numDecimalPlaces or 0)
   --return math.floor(num * mult) / mult
end

If you dont need so much control on scaling, or need seamless tiling, or may be performance is very important, you can use this snippet from Creeps 2 by WarpZone

Seeing as your Spaceship Lab filter is for FF9 would it be safe to assume this is as well?

Some fixes in code

Code

function prepare()
   -- This function is called once,
   -- before the rendering begins.
   -- Use it for querying non-mapped
   -- inputs and precalculation.
   is_X = get_checkbox_input(X_OR_Y)
   if (is_X) then
      max = SEAMLESS_REGION_WIDTH
   else
      max = SEAMLESS_REGION_HEIGHT
   end;
end;

function get_sample(x, y)
   -- Image generation code goes here.
   local remapGradient = get_sample_grayscale(x, y, GRADIENT)

   if is_X then
      x = round(x)
   else
      y = round(y)
   end;
   local globalV = get_sample_grayscale(x, y, IMAGEGRADIENT) * max
   remapGradient = remapGradient + globalV
   return remapGradient, remapGradient, remapGradient, 1
end;

function round(num, numDecimalPlaces)
  local mult = 10^(numDecimalPlaces or 0)
  return math.floor(num * mult) / mult
end
