A specific Roblox bundle, Pencil Body (RECOLORABLE), appears to be abusing a glitch that causes the lower legs to become invisible or misplaced when equipped. This specific bundle is against the rules of Spam in the TOS stating, “Roblox prohibits disrupting or misleading others on the platform. This includes:
Deceptive, sensational, or otherwise misleading content or metadata used to inappropriately drive discoverability or engagement.” Which this bundle replicates a Roblox Asset Linked here (specifically the legs, they are popular among roblox users) using this bug.
Reproduction Steps
Equip the Pencil Body (RECOLORABLE) bundle.
Observe the lower legs of the avatar.
Note: The exact cause of this glitch is unknown, but it consistently occurs with this bundle.
Expected Behavior
When equipping a bundle, all limbs should properly render and follow the standard avatar structure without any unintended invisibility or misplacement. When uploading this bundle, usually it wouldn’t be accepted and would fail validation rules. This user had to use some glitch or exploit.
Actual Behavior
Lower legs of the avatar become invisible or shift to an unintended position.
This occurs specifically with the Pencil Body (RECOLORABLE) bundle.
May be related to avatar scaling or rigging issues.
Additional Notes
This issue may be caused by an unintended interaction with avatar scaling or limb attachments. If possible, further investigation into the bundle’s rigging and how it interacts with the avatar system is needed. This is most likely a glitch with how the rigging works with the body parts.
Attachments
It also shows the leg parts having low vertex counts which could contribute to this bug.
Suggested Fix
Review the rigging of the Pencil Body (RECOLORABLE) bundle.
Ensure that it follows standard avatar attachment rules.
Patch any potential exploits that allow for avatar limb displacement.
Another bundle uploaded by the same creator is abusing this but as well, with both lower legs and feet missing.
Also, recently there were a few bundles using a glitch that involved layered clothing. These bundles don’t have it but they may have similar effects on the bundles.
Thank you for flagging this. We took a look at this, and noticed that the lower leg and feet geometry were both scaled to miniscule sizes, and then moved far below the upper leg geometry. We’ll have to investigate how this happened, and determine if any rules have been violated.
On behalf of OP, thanks for looking into this. Since this has now been officially acknowledged, I want to note that I privately consulted an engineer about this specific bundle, and they explained that since the entire leg is classified as a single body part, making 2 out of 3 sections invisible does not violate any current validation rules. I wasn’t fully satisfied with this explanation, however, and I believe bundles like this which closely resemble the infamous Korblox Deathspeaker leg shouldn’t be allowed. Please keep us updated if your findings differ from what I’ve been told.
Many bundles like this were taken down in the past such as for example the pirate bundles. This breaks the rules for invisibility, there should be no question about it. The bundle might seem innocent but it is clear the intention was to replicate korblox.
Totally agree. The inconsistency in which bundles are taken down and which are allowed to remain is frustrating, and a clear policy needs to be established to eliminate this grey area. Bundles that exploit invisibility in this way should not be an exception—layered clothing items that do the exact same thing are consistently removed, as are bundles that achieve this using EyebrowAccessorys. Yet, because these particular bundles rely on a newly discovered method that doesn’t require additional accessories, they’re somehow permitted.
It almost feels like engineers refuse to acknowledge that a loophole in bundle validation exists and assume that every bundle passing validation is acceptable by default. However, the fact that similar bundles have been removed in the past proves that this is an issue worth addressing.
These kinds of bundles are also widely criticized by the community, and I really hope that’s taken into account during internal discussions. Their resemblance to Korblox Deathspeaker is undeniable, and at the very least, some form of moderation needs to be in place to handle cases like this consistently.
