Front Facing still produces backward quads

mugathur

We've got a character on this project who had various body parts disappearing. We realized that they were backwards facing so I turned "Front Facing" on and it fixed most of the problem. However, there is still one part (hand) of the character that still has a backward facing normal. Any idea on how to fix it?

By the way, we're using Unity 3.2.something runtime.

Here is the view from the front

And here is the view of our inspector setup.

Thanks in advance. I'm happy to send the spine file over if it helps.

(1) Front Facing doesn't affect Normal direction. It affects triangle winding.
Front Facing is specifically for lit shaders that have specific requirements (or if used lit shaders meant for 3D on Spine's meshes which are meant for 2D). The front-facing requirement is only in shaders that cull the back faces of triangles, which relies on triangle winding direction and not the normals.

This is actually not compiled by default in 3.3 because it's such a rare case, involves extra overhead, and is easily fixable without resorting to front-facing if you made the shader yourself;
I personally recommend trying the ToddRivers Sprite Shaders if you need an alternative to some 3D shader you're using.

(2) If you really like that shader you're using as it is, you can send your project to unity@esotericsoftware.com and we'll see what case it was missing.
