I don't know if any of you have ever used sPATCH, but it is the only modeler that I own/use/understand. The problem is that in POSER my models often have several areas that look invisible in the preview pane(they render just fine, though! ) I just submited a product for review for the market place, and it was rejected for this reason. I was told I had "inverted normals". I did try the grouping tool in POSER and clicked the "invert normals" button,but it just made the same parts invisible from the opposite direction.Any help, please ?!

If you have UVMapper Pro and the are in question has its own material, this would be simple to fix. Just load it in, select the group by material and invert the normals. Then save it back out. If not, go download WINGS3d at the link above and load in your OBJ file. Select the piece that's flipped, right click and flip them back.

Yes, that is what we have to do, go to UV mapper and invert your normals and then resave, you should be all set. Sharen

Sometimes Poser can fix the problem if you select "make surface normals consistent" in the render options. Generally I've had to fix them in more long-winded ways, though.

thanks for the quick responses, however they aren't helping...the LEFT side of my model is invisible when viewed from the left. I tried inverting the normals using wings3D, UVmapper, Poser's grouping tool, and the "flip normals" when importing. All 3 ways resulted in the RIGHT side of my model being invisible when viewed from the right...???

Try welding your surfaces before importing. might help. sounds like half are flipped because of a mirror command and when you flip them you just reverse the problem. in UV mapper just select half the model and flip it. just random suggestions from what info you have given. good luck J.B.
