2) Place an empty at the bottle's centre of mass, so-to-speak. How do you tell which normals are flipped in and which are out zanzio (zanzio) August 12, 2018, 9:24pm 2. Blender 2.8 How Show/Hide Face normals 2 Likes.

I'm wondering if anyone might be able to write a script for me, that would work something like this: 1) Import my mesh, set its base at 0:0:0. Blender Artists is an online creative forum that is dedicated to the growth and education of the 3D software Blender. Note that this allows you to precisely control the direction ( not the orientation, which is always perpendicular to the face) of your normals, as only the selected faces are flipped. I've tried just about all the normal management functions (there aren't many) but it literally comes down to me having to individually select the reversed faces and and then flipping the normals. This will reverse the normals direction of all selected faces. Using a solidify modifier and applying it would work too. obj file.įor the most part, the normals all face out as should be the case, but around the embossed area the normal direction becomes random - some face out, others face into the bottle mesh making glass rendering impossible. If so, you cant really have double sided normals (for a single face), you must duplicate the mesh and flip the duplicated faces inwards (so the normals point inwards) to get interior faces. The mesh is pretty evenly divided until it gets to the embossed logo where the mesh gets very, very dense due to the bevels. A collegue has modelled, in Rhino, a small transparent plastic bottle (the type commonly seen holding small amounts of cosmetics etc.) with an embossed logo on the wall of the bottle.
