There are two glitches/issues with T_He_SetHarbor_DoorTrap_01 model:
Green light/parts visible from the bottom
Visible splits in the middle of the model
As seen on screenshots above, you can see something akin to imperfect placement of shell in the model - it gives it a look as if there were four corner parts of the doortrap mixed together instead of one smooth surface.
