Is there any fast way to get all normals on the same side ? I tried ctrl+n … it should recalculate all normals outside…but still some are wrong.
select the wrong ones in face select mode, and press w>flip normals
Yeah…i know…but i asked a fast way…it is very annoying to find all wrong ones and then flip them…
Are you sure all the vertices are connected?
Maybe try a remove doubles.
