Parts of mesh become invisible at certian angles

Question

Hey,

I am importing an fbx model but parts of it are invisible in the scene And game at certain angles.

Attached image SS-1 = the full model - You can see that some parts of the mesh are invisible Attached image SS-2 = closeup of an invisible mesh selected

Any ideas what's going on?

There are two options to fix this; For me the second one worked because my model had to rotate constantly.

1- If your model isn't going to rotate just fix the normals. Normals facing backwards are not rendered if Cull Back (default) is set in the shader.

2- If the model is going to rotate you need to change the Cull Settings in the shader; use Cull Off instead of Cull Back. See unity docs: https://docs.unity3d.com/Manual/SL-CullAndDepth.htm

Also you can download default shaders from Unity download page.
