>>2944764The normals are unaligned, realign them to face the outside either through manual value input on the vertex tab (use [1] point selection in PMXView while on the vertex tab of PMXE) or with a quick but mindful inversion and/or averaging. Vertices located in the same spot should have identical normals (averaged to each other).
