title: Why does my mesh disappear in Unity when I add armature and subsurface modifier together?
body: <p>I'm making a rigged model by using Blender. And the rigged mesh seems okay when I run the project on Unity and android device as well if I didn't add "subdivision surface modifier" from Blender. But if I add "subdivision surface modifier", it normally runs and seems okay on Unity, but the mesh just disappears when I build the project and test it on my android device.</p>
  
  <p>I've found out "subdivision surface modifier" affects the result in some way. My android device is not that old one(Android version : Oreo/API level 26), and I've tried adjust settings like minimum API level or target API level from Unity, but it didn't work at all.</p>
  
  <p>I've been working on this almost three days already. Could anyone please help me out with this issue?</p>
