You’re staring at a wall. It’s a thin, gray, annoying slab of digital concrete in a Roblox obby, and the only way forward is through a gap that doesn't exist. Or maybe you're playing a speedrun game where every second counts. You’ve seen other players just... vanish through the geometry. They make it look like magic. It’s not. It’s a physics exploit that’s been around since the early days of the platform.
Learning how to corner clip in Roblox is basically a rite of passage for anyone getting serious about high-tier obstacle courses. It’s glitching. Plain and simple. But in the world of Roblox physics, glitching is often just a high-level mechanic that the developers (sometimes) leave in for the sake of the speedrunning community.
The Physics Behind the Glitch
Why does this even work? Roblox uses a physics engine called PGS (Physics Gaming System). It calculates collisions based on the position of your character’s "Hitbox." Usually, these calculations are rock solid. But when you jam a character model into a 90-degree angle and force a camera shift, the engine gets confused. It tries to resolve the overlap by pushing you to the nearest "open" space. If you’re positioned perfectly, that "nearest" space is actually on the other side of the wall.

It's sort of like trying to squeeze a marble into a corner until it pops out the other side.
Most people think you need a high-end PC or a specific frame rate. You don't. While a higher FPS (frames per second) can make the movement feel smoother, a standard 60 FPS is plenty. What actually matters is your avatar’s package and your Shift Lock settings. If you aren't using Shift Lock, you might as well be trying to walk through a real brick wall. It’s just not going to happen.
Preparation: Setting Up Your Avatar
Before you even touch a wall, look at your character. If you’re wearing one of those massive, bulky "Rthro" packages or a giant robot suit, you’re making life hard for yourself. Most pros use the standard R6 blocky rig. Why? Because the hitbox is predictable. It’s a rectangle. Rectangles love corners.
- Enable Shift Lock: Go into your game settings (Escape key) and make sure Shift Lock Switch is set to "On."
- The R6 vs. R15 Debate: Most obbyists swear by R6. It has fewer moving parts, which means fewer variables for the physics engine to mess up. In R15, your limbs flail around more, which can actually bump you away from the wall instead of through it.
- Check Your Ping: If your ping is over 200ms, the server might "rubberband" you back. You'll think you clipped, but a second later, you're back where you started. It's frustrating.
Step-by-Step: The Classic Corner Clip
Okay, let's get into the actual movement. Find a thin wall—ideally one that is 1 stud thick or less. Thick walls are much harder to clip through and often require different methods like "Laugh Clipping" or "Dance Clipping," which are different beasts entirely.
The Positioning
Walk up to the corner where the wall meets another surface. You want to wedge your shoulder right into that 90-degree crease. Don't just face the wall; turn your character so your side is hugging the corner.
The Camera Flick
This is where the magic happens. Zoom your camera all the way in so you’re in first-person mode, then tap your Shift Lock key (usually the Left Shift). Now, rotate your camera hard into the wall while simultaneously walking forward and sideways (W and A or W and D, depending on the side).
It’s a flicking motion. You’re essentially forcing your character’s arm to intersect with the wall's geometry. When the engine realizes two things are occupying the same space, it panics and shoves you through.
Variation: The Dance Clip
If the standard method isn't working, some players use emotes. The "/e dance" command is a classic. By starting the dance animation, your character’s hitbox shifts and rotates in ways that standard walking doesn't allow.
- Type
/e dancein the chat. - While the animation is playing, zoom in and use Shift Lock.
- Time your camera flick with the moment your character’s limb swings "into" the wall.
It takes practice. A lot of it. You’ll probably fail the first fifty times. Honestly, that’s normal.

Why Some Walls Refuse to Cooperate
You’ll find walls that simply won't let you through. This isn't usually a "skill issue." Modern Roblox developers have gotten smart. They use a few different tricks to stop people from how to corner clip in Roblox in their games.
Anti-Cheat Scripts: Some games have scripts that check your position every few frames. If the script sees you moved through a solid object without a designated door, it kills your character or teleports you back.
Thick Collisions: If a wall is 3 or 4 studs thick, a standard corner clip won't work because your hitbox can't reach the "air" on the other side. You’ll just get stuck inside the part.
Invisible Barriers: Developers often place a second, invisible wall slightly behind the visible one. Even if you clip the first one, you hit the second.
Surprising Truths About Clipping
Did you know that your screen resolution can actually affect your success rate? It sounds fake, but because the camera's "flick" is tied to mouse sensitivity and pixel movement, playing on a tiny window versus a 4K monitor changes the timing.
Also, the "3-way corner" (where two walls meet a floor) is infinitely easier to clip than a "2-way corner" (just a floating wall edge). The floor acts as a physical anchor that prevents your character from falling down, allowing the engine to focus entirely on horizontal displacement.
Mastering the Muscle Memory
To get good at this, you need a training ground. Don't try to learn this in a high-stakes competitive game. Go to a "Difficulty Chart Obby" or a dedicated "Glitch Practice" realm. These games often have walls specifically designed to be clipped, with markers showing you exactly where to stand.
Watch your character’s feet. If they’re jittering, you’re in the right spot. That jittering is the physics engine fighting itself. That's the moment you flick the camera.
Actionable Next Steps for Aspiring Obbyists
Stop trying to clip through every wall you see and start with the basics.
- Switch to R6: Go to your Avatar editor and ensure your scaling is set to R6 for the most consistent hitbox.
- Practice the "W+A" flick: Most people find clipping to the left easier than clipping to the right. Master one direction before trying the other.
- Use a Metronome: This sounds crazy, but some high-level speedrunners use a 120 BPM metronome to timing their "Dance Clips." If you can time your camera flick to the beat of the animation, your success rate will skyrocket.
- Record Your Gameplay: Use OBS or the built-in Roblox recorder. Rewatch your fails in slow motion. Usually, you’ll see that your camera flicked a millisecond too early or your character wasn't deep enough into the corner.
- Learn the "Truss Clip" next: Once you've mastered corners, try clipping through trusses. It’s the same principle but requires a vertical camera flick instead of a horizontal one.
Physics glitches are a fundamental part of Roblox history. While the developers at Roblox Corp continue to update the engine, the community always finds a new way to slip through the cracks. It's a constant game of cat and mouse. Get in there, find a corner, and start flicking.
