After I created a model then export it.In other programs such as Iclone 6 or Substance painter.The Object loads up inverted or with Backing Culling set.But the thing is i did not check the box in blender under the shader tab to set Back Cull on the model.While working on the object in blender its ok but after a export to another program its inverted.How to i fix this exporting problem.Also if i export it to Maya 2013 it also looks ok.
