Cartographic Polygons for unity

Hi, is there away to cut out or hide parts of the terrain in Unity. like using the Cartographic Polygons in Unreal.

Thanks

We plan to add it eventually, but don’t have a definite timeline for it currently. In the meantime you can create a custom material that masks out part of a model. The main downside is that tiles entirely within the masked-out area will still be loaded.
