Exporting OBJ from Rhino to Adobe Dimension

We have an obj made in Rhino that when imported into Adobe Dimension, breaks up into triangular faces and is generally unusable. Similar to the problem in this post: https://community.adobe.com/t5/dimension-discussions/export-import-issues-from-rhino-to-adobe-dimens…

We tried the export settings here but weren’t successful.

Is there anything particular we should take a look at in the Rhino model, regarding the faces, UV meshes (although we are not applying any material in Rhino), or polygons? Why is this issue happening?
