ObjExporter and meshgrouping. Unity exports obj's as multiple combined meshes.

I cant figure it out, I've ruled out Maya's importer by also importing obj's to 3dsMax and Blender. Using the mesheditor asset from the store I can export meshes in one shape but I want a quicker alternative. No matter what I try the mesh is exported as multiple pieces. This is happening in Unity as the original mesh is one solid piece. I'm also trying to find the correct obj/normal scaling but I'm getting close on that front. Mesh editors correctly exported meshes are peeking over the right edge of the photo. Help please.

 

Ugh,... Unity's import setting "generate lightmap UVs" was the culprit... wtfffff
