World machine textures to Unity 5 no tool for splatmap

Hi, hope everyone is fine. I am trying to texture my terrain created in World machine 2, to Unity 5. There is no way I can do it, there was splatmap option in previous unity versions, but now it doesn’t exist. I’ve searched everything I could, but found only one answer which was to use Terrain Composer, which is not free on unity asset store. How can I add texture to my terrain, the heightmap and terrain looks all good but no texture. Is there a way to export ultra texture (2048x2048 atleast) in World Machine ? Thanks.

leave this.
