  Hello,i created a wavesurface in beldner, then i flipped it around y-axis.in the renderng code, i turned on the backface culling and the result is:Demo picture using backface cullingDemo picture with no backface cullingi saveed the model to wavefront obj, and i tested render this wavesurface in every ways (triangles, vbos, triangle_strips using nvtristrip). in blender 2.41, everithing is fine, i can't test there this problem.i created 4-5 models, and the half of them suffer from this problem...has anybody met this problem?Thanks in advance...[Edited by - fazekaim on July 11, 2006 3:20:20 AM]
  update:if i don't flip the model in blender, but in my code, the model works fine.i loaded it to 3ds max, and save-it and the problem is still exists...a have no idea what cause the problem...;  And what is the problem exactly? I can't tell much from the picture. Those holes in the image? What is it supposed to look like?   ;  update2: if i don't add a subdivision layer to the surfce, the problem is gone.so, the cause of the problem is probably the subdivision layer, but i don't know why.   ; Cross post. Closed.
