Once and awhile when I try to subdivide an object, around level 3 , the geometry will go wacky. It looks like some faces get skewed into infinity. See attached pic. The strange thing is this particular object was working fine for awhile. I think I went back to maya and made some minor changes and then re-imported to start over. Now I have this problem with it. I checked for non manifold geo and didn’t find any.
Thanks!
