My mesh has a big 'hole'

It looks usual as you can see. However,

when i try to move the view nearer to this can, there is a strange big ‘hole’. How can i solve this problem? By changing the LOD?Is my graphics card not powerful enough?Or something else?Please answer!!!

Thank you!


You need adjust Near Clip Plane. After adjust, save project and reload it.

Near Clip Plane = 10.0 (Default)
