Question custom canonical face mesh appear in front of face

I tried to make an augmented face using ar foundation and made a custom 3d hair shape with canonical face mesh, but why only 1 worked properly, but the others appeared in front of my face. even though I made a custom 3d and the installation steps are the same.
Does anyone have a solution?

 

To occlude virtual content with real world objects, you need real world depth information using a system such as AROcclusionManager.

Checkout the SimpleOcclusion scene in AR Foundation samples.

Do note that occlusion does not work with the front-facing camera on most devices.
