View Full Version : weird importing things

06 June 2009, 09:45 AM
weird things happen... shown in the attached picture. the left is zb, the right is maya with two sided shading turned off, so you can see none of the faces are black so none of the normals are going into the mesh (also comfirmed by toggling show > polygons > normals

i export out the obj and import it to zb using default export options

the mesh has been cleared of history,
the normals are facing outwards
the transformations are frozen

when i import to zb it gets inverted as if the normals are reveresed
so i try reverse the normals, export, then import back into zb
the same result... it still looks like it's got reversed normals

if i export this with other pieces of geometry with fewer polygons those objects get inverted too, yet if they are imported by themselves they turn out fine

if i export this with another piece of geometry one that's got more triangles it gets corrected

if i select a whole lot of faces in this piece of geometry and reverse the normals (so that a few have inverted normals) then it imports correctly...

all the other pieces of geometry show up correctly in zb, even the ones made in a similar fasion as this...

any idea what's happening?
