Lanscape import problem

One question regarding importing landscape on TW… When i import a FBX (in this case from revit) as geometry TW import all ok (image on rigth in white)… When i use the same FBX as landscape import TW make a total diferent mesh (on left in green). … No matter the settings or file format the import as lanscape it isn´t working ok, beacause the geometry it is not rigth… And in case of archviz it must be the same as exported to be as in project…
Does any on have the same problem or issue?

Hello.
It looks like your landscape has not enough geometry.
You need to subdivide your landscape mesh in an external program such as Blender (if it’s not possible in Revit).
