Using Landscape Painting for tiled maps

So I am trying to develop some method of using the landscape painting tool in order for artists to be able to paint tiled levels in Unreal. One option that works in very small scales is using the component brush, but that seems to take too much memory for just a 32 x 32 tiled map. We ideally want to paint textures on these tiles and eventually be able to use these tiles for game-play purposes.
I feel like I got close to solving the problem but ran into a wall when I was unable to find the layer blend weight using the Landscape coordinates or UVs. I could have used the layer blend weight at a specific point in the landscape to color an entire tile that color/texture. So if anyone could help me figure that one problem or help me figure out a different solution, I would really appreciate it.
