Object2Terrain Error

I am using the Object2Terrain script. However when I try create a terrain based on a circular mesh the terrain created is always square shape and this error appears.

Expanding invalid MinMaxAABB


Invalid AABB result

Thanks in advance for any help.

Unity does not support any other terrains therein square.

The MinMaxAABB is because a script has probably created a not valid bounding box for the object.

Terrains are always square, since they’re stored as a 2d heightmap.
