Originally posted by vladimirjp is there a way to catch the state of normals? to know what direction they are facing? if they are facing away from camera or not. im tring to writte a script that finds all objects who's normals are inverted. and make them point in the right direction. I think there is a problem with this concept. Normals can face away from camera and still be just fine. I'm talking about the faces on the back side of the object (which the camera cannot see). Might be safer if you just investigate the normals of the selected faces only...
