[![My Pictures are in reverse order This is what happened when I used a subdivide modifier Appears to have 2 sets of polys
][1]][1]I joined 2 meshes together, adding eye socket to the stalk for the eye on a crayfish. It almost looks like a ghost set of polys are making a translucent layer over the regular polys. The polys above the join edge are shinier and darker and I've tried to reset the material and that didn't help. I deleted a couple of rows of ploys and rebuilt it and the shiny just comes back. Ctrl L selects the whole model so the meshes are joined. The first picture is what happened when I tried adding a subdivision modifier. [![enter image description here][2]][2]
