Im making my own level and when i go to export something im getting a gay error. I took two object, created new polygons to make it one object and no im getting the couldn't update edge #326 and so on. I know this has been asked but never have got a real answer so how the heck do i fix this error?

import you .wrl file and lok for the problem and fix your open edge by create a new edge where it should be or making sure a edge isnt the wrong way around.

Thanks for you help god i hate fixing errors.
