Holes in mesh on import from Blender

[arumiat1]

Hi all

I am importing a .blend file by placing in the Assets folder of a Unity project. Although these are single objects in Blender, the larger polygon meshes end up being split into 2 smaller meshes with overlap like so…

I’ve followed this thread in terms of removing doubles and calculating normals but has no change on the meshes inside Unity.

These are fairly dense meshes, is this likely to be the cause of the issue?

Thanks in advance

Unity splits meshes that have too many polygons for it to handle. You need to get it down below 69k triangles for Unity to not split the mesh.

Thanks drew, that sorted it.
