Importing FBX triangulates I downloaded this old 3DS max file for a dog, then exported it from Max as an FBX using the settings you see in the image on the left. I imported it to Blender with the settings you see on the right and it triangulated the mesh. I looked at another answer that said to uncheck triangulate and preserve edge orientation on the Blender import but there are no such options. I tried checking and unchecking multiple items and reimporting it to the same triangulated result. I have also tried exporting and importing as a DAE but that did not work. Unsure what do try next.



Any suggestions? For a way to import as quads only or detriangulate.
Blender has an ability inside edit mode to convert triangles to quads. Press ALT + J with everything selected, or by selecting everything, CTRL + F for Face Menu, then Tris to Quads.

Edit: Something that might take you the rest of the way there is the Quadriflow Remesh tool. Its available in Blender 2.81+. As with all things unknown, I'd test it on a safe duplicate.
