View Full Version : How To Recreate The Walkthrough Materials Glitch (Post-Leerdammer)

Introduction

N.B. this tutorial only applies to LBP1. See this thread (http://www.lbpcentral.com/forums/showthread.php?48030-Walk-Thru-Walls-Glitch-Rediscovered!) for the LBP2-equivalent.

For reference, the traditional way to create these, prior to Leerdammer, was:-


Create a block of material.
Attach a creature brain to the block.
Attach a one-shot switch to the brain.
Trigger the switch, and immediately pause.
Capture the block of material.
Emit it with an infinite lifetime.


While I was experimenting with creating walkthough materials during a rollback, I noticed something kinda strange: when I patched back to Leerdammer, I noticed that although this process no longer works, if you had a block you'd made as far as step 5, you could still re-emit with infinite lifetime, and it would remain stable.

I theorized that the 'fix' for this process didn't involve any changes to the way in which emitters worked, but that they'd just added a flag to the material to indicate it was 'killed' and couldn't be re-emitted with an infinite lifetime. However, in order to retain back-compatibility, I wondered if it they'd also made it such that, if a material was killed prior to Leerdammer, that this new flag wouldn't get set.

Turns out that's the case, so you can actually make walkthrough versions of materials which weren't patched into the game until after Leerdammer (e.g. PotC, Incredibles, etc.) as long as you have a walkthrough material which was made prior to Leerdammer.


Method

First of all, you need to obtain an existing walkthrough material. If you don't have one already, you can pick some up from my level (http://www.lbpcentral.com/forums/showthread.php?29559-Garden-of-Goodies). Any material sample in the top row of any of the material palettes will work just fine. If you do intend to use one of these, ensure you detach and delete the DM blackplate before starting (so that the material sample is smearable), otherwise it doesn't work. Not certain why.

Secondly, material change it to the material you want. This will also have the effect of making it solid again, but it doesn't matter.

Now all you need to do is follow the traditional method from step #2 onwards as described in the introduction. The result should be a stable walkthrough material.


Notes

Note that the ability to stabilize (i.e. re-emit with infinite lifetime) a 'dead' material is the same technique used for creating the following glitches...

Thin/theck/thack gas
Plasmafied materials

...so those are also possible to reproduce post-Leerdammer.

Nice find Aya. You truly are the Master of Glitches.

Awesome! Now I've got to try it on objects --meaning I've gotta' do a rollback to an earlier patch where dead objects (like knives) could be stabilized, then update to 1.18 and use a plasma ball to re-kill it and see if I can get a stable plasma blade.

(Note to self, silence Aya :kz:)
:p


On another note, I didn't know this was patched, are you sure it is?
Because I've been using it multyple times with materials directly from the popit without any problems.

Fairly certain, but I wouldn't say I was 100% on it. Bear in mind I'm speculating on the behaviour of source code I've never read.

Now you need to try this with anti color! :p


Great find Aya! :)

I wonder, would the same thing be true for other glitches pre-leerdammer? Say, if you had a cow-glitch material, changed it to cardboard, and tried to redo the cow glitch into dark matter, would it work?

But thanks for this! It helped me a ton for some walkthrough marvel cardboard!

Mm focused more upon the cow glitch than the walkthrough material glitch, and I think I've tried that... It doesn't work, at least not by my reckoning.

thnx for the info. Did u know that u can make a thin version of this too. I used this glitch in one of my levels to make a mirror.

Hey Aya, I just found a method that works with both materials and objects, post Leerdammer:
1. Get the desired object/material, kill it with a creature brain, pause the level, as usual.
2. Attach a string to the dead object/material. Leave the other end of the string unattached.
3. Capture the dead object/material, and perform the chrome glitch (http://www.lbpcentral.com/forums/showthread.php?36483-Very-Rare-chrome-glitch) on it.
4. Select the string atached to the dead, chrome-glitched object/material. It will snap back to being tangible again, but will be unselectable.
5. Create a piece of material and glue it to the object/material, and then select that new piece of material.
6. The dead object/material will now be stabilized! You can now just delete the other piece of material.

Interesting. I've mostly given up with LBP1 tho', so we'll have to start glitch-hunting anew when LBP2 comes out. :)

How do you change the material from walkthrough , back to normal?[

Only by material-changing it to another material.

in LBP2, step 5 of the process doesn't work; I can't capture the object.
However, if you create an emitter, you can select the object and the emitter will save it. The emitted object cannot be captured, so you are stuck using the emitter every time you want to create another copy of your object.

I found another way that you CAN capture the object. Immediately before step 5, use the horrible gas tool on the object, and capture the horrible gas object. You can retrieve the gas object and use the de-lethalize tool to restore it the to original material that you can still walk through.

This tutorial is only for LBP1, hence being in the LBP1 section of the forums. There's an LBP2 version here (http://www.lbpcentral.com/forums/showthread.php?48030-Walk-Thru-Walls-Glitch-Rediscovered!). I probably ought to update my sig, as most of the tutorials don't apply to LBP2.

Which was also mentioned in post #3 of the thread I linked to.
