On two meshes on my last project I managed to do something strange. In the 3d view/camera view they look fine, but once you render the mesh it flattens onto a 2d plain aligned to the camera. Then stays that way. Not sure what I did to get that to happen but it would be nice to know so I don’t do it again on accident.
Attached are before and after images of what’s going on. along with the blend file.
Thanks in advance.
