Nanite: avoid holes in a ground made of planes scenario

Hi, I have made city streets with houdini, I am exporting it as a few hundread tiles, and when turning it to nanite, it introduces holes in some areas. Can I avoid them? Thanks

These holed dont even appear at a distance, they are visible no matter how far camera is

Hello @FAXCORP
Mmm open the mesh and look for nanite fallback, set to 0. Not sure but in my mind makes sense jaj
