[HELP] Somehow Alembic's object is hidden.

Hello. everyone.

I am currently importing Alembic files generated using Houdini into Unity.

Although it is the loaded Alembic object, if you rotate it or move it with the camera, somehow Alembic object will disappear or appear from the camera.
This phenomenon also occurs when you rotate the Scene view.

Do you recognize the cause of such a phenomenon?
I am very happy if you let me know if there is one.

 

It’s acting like the bounds are wrong, but I’m not familiar enough with Unity’s alembic support to offer much more than that.

 

Thanks a lot.
I will search again :~)
