Just uploaded a few conversions (can add more if you have something specific). Take a look here: Deer
One is a direct (1 to 1) conversion the other a NURBS based one with 6k patches. I would guess that the 1:1 version is too big and the Nurbs one may have some errors...
This was done using InStep Studio 3D (https://instepstudio3d.com/) if you want to give it a try yourself, I can provide help with that...
