[3DS MAX] Invalid Vertex Index

[BetterThanLife]

So I've exported an entire map as .obj, just something small to see if I can open it up in 3ds and I'm getting this error. Anyone have any idea how to fix this?

Hmm. I tried importing as a single mesh. Technically it works, I mean I get something imported. But the geometry is messed up you can't even tell what it was supposed to be.

try to export from selected only and select all of the map but only mesh! then it should work
