The '''Hall of Mirrors''' effect is a rendering [[glitches|glitch]] present in many games, including ''[[Halo 3]]''. The glitch occurs when nothing is rendered to a particular region of the screen.
The '''Hall of Mirrors''' effect is a rendering [[glitches|glitch]] present in many games, including ''[[Halo 3]]''. The glitch occurs when nothing is rendered to a particular region of the screen. This glitch can be recreated in the [[wikipedia:Unity (game engine)|Unity]] game engine by turning off the "Clear flags" effect, then entering play mode.

To be more specific, the frames of animation are created by the rendering engine and stored in a [[Wikipedia:Framebuffer|framebuffer]]. The framebuffer is basically a storage area for frame data. When a frame is displayed, it is sent to the framebuffer.

The hall of mirrors effect results from the fact that the framebuffer is not cleared between frames.  That is, the data from the previous frame is not deleted from the framebuffer before the next frame is drawn, so if the next frame has transparent regions, then the un-deleted data from the previous frame will show through.

There is also an explanation for the phenomenon that occurs when the hall of mirrors effect is seen during split-screen gameplay. If the same framebuffer was used for each of the split screens, then Player 1's screen would show through any transparent areas on Player 2's screen, because Player 2's screen is effectively drawn over Player 1's.{{citation needed}}

There are a variety of ways to view the effect. Any time a player gets outside of the map or sees a gap in the level geometry, they may see the effect.

If [[Panoramic Camera Mode|Pan Cam]] is used to get outside of a level's boundaries, then the hall of mirrors glitch is almost guaranteed to appear.

During the part that the [[Type-47B Scarab|Scarab Tanks]] appear, two players must be on a Mongoose, and drive them against a door <!-- which door? --> and the passenger to alight. If done correctly, the game will freeze for 10 seconds. The Scarab will disappear, and if you go to the door, you will see the hall of mirrors effect.

At the beginning of [[The Covenant (level)|The Covenant]], after taking out the (normal) [[Type-26 Wraith|Wraith]], if you climb up the surface of the tower you are supposed to enter, you will find a rift in the snow that shows the hall of mirrors effect.

Another hall of mirrors effect occurs in this level. Start the level at '''Rally Point Alpha'''. Get into a [[AV-14 Hornet|Hornet]] and fly to the second tower. Look directly at it and hover down to the left. You will be facing a ledge; fly towards it. Park the Hornet onto the longest ledge, and face the rock wall. Turn left and move forward to a crack in the rock. When you look into it, you will see the hall of mirrors effect.

The glitch can be done in [[Sandtrap]] in [[Forge]]. Go into Edit Mode, and fly into the chasm-like structure and face the high dunes that cover up the barrier. Look right, and move forward into the indention of top of the wall just below the ledge and zoom in. You should see the hall of mirrors effect there.
