Ha, I just spent an hour hunting down the weirdest "bug". Turns out that if I apply a morph to write out the result as an OBJ, I should either recompute the normals or delete them, so that when I test the output in Blender, it doesn't look like it applied the morph to the shoulders and legs, but not the abs. *headdeskemoji*

Don't mind me. On with your regularly scheduled program.

Most programs calculate normals on load. I don't think I've ever encountered an instance where deleting the vn lines from OBJ had any effect upon importing to various environments. It's my understanding there are certain instances where Poser recalculates normals on the fly during certain processes, or so I've heard. Can't remember the particulars but I think it involved solving some scene bug, and it was a workaround, perhaps discussed by Bagginsbill.
