When I export a masked mountain in FBX, the polygons are messed up.


I am working on a gnomon workshop CREATING A MONOLITHIC CITY IN UNREAL ENGINE 5.

I have a problem in the process of Gaea -> Houdini -> UE5.

I exported a map from Gaea, loaded it into Houdini, polygonized it, and loaded it into UE5, but when I export a mountain masked in Houdini as FBX, the polygons are messed up.

The unmasked ones are fine, I want to export them in FBX, not alembic.

Is there a solution?

The file did not fit in 15MB and could not be attached.
