How to use tiled weight map in layer info with tiled terrain?

Hi all,

I have exported some tiled slope with tiled terrain in world machine. But how to use that inside unreal engine?

I am ok with importing tiled terrain but the tiled slope as weight map in layer info.

I had tried load all the terrain (4x4 tiles, 8km x 8km) and import the untiled slope(2017x2017). My unreal editor stopped after that.
Now I’m creating 16 layer info for each layer and importing different tiled slope as weight map and it works.
The problem is I’m planning to make smaller tiles afterwards, this workflow will make me crazy if I make something like 16x16 tiles or even 32x32.

Is there any method to use those weight map by tile? Or even other method can do the same effect?

Thanks!
