   Why it must be exported as triangles

   When a normal map interpolates the asset's normals,

   the bake interpolates based on the low-poly normal direction.

   The resulting normal map carries information of the form ( low-poly normal direction used → high-poly bake → normal map corrected based on the low-poly normal direction ), so the low-poly normal direction must be locked by converting to triangles ( without converting to triangles, the triangle direction can change as the asset is passed around )
