Rthro

Rthro (previously known as Anthro, short for Anthropomorphic) is the second most recent addition to avatar types for Roblox, first revealed during Roblox Developers Conference 2017. The term "Rthro" is most likely a portmanteau of the words Roblox and anthropomorphic.
These avatars stand out as being much more human-like when compared to the traditional "blocky" appearance that is commonly associated with Roblox avatars. With more refined joints on the avatar than R6 and R15, animations are also more human-like. Most existing catalog content, such as hats, shirts, and pants are compatible with this avatar type.
Rthro scaling was fully released to the public on October 22, 2018,https://devforum.roblox.com/t/announcing-unlocked-avatar-scaling-expanding-the-roblox-universe/189292/84 and the first Rthro-specific bundle known as Knights of Redcliff: Paladin (along with the Rthro Animation Package) was published on October 23, 2018. An official blog post about Rthro can be found here.
==Scaling==
Rthro characters use the Body Type scaling option. 0% is a classic R15 character, while 100% is a full Rthro character. Body Type makes your character taller, and more slender/human-like.
The Proportions scaling option is also sometimes used with Rthro characters. Proportions makes your character a bit shorter with slightly wider hips. (Proportions will only take affect if your Body Type is greater than 0%.)
Bundles tagged with "RTHRO" in the Catalog automatically set Body Type to 100% when equipped. Some Rthro bundles will also set Proportions to 100%. Many Rthro bundles are designed to be used with Body Type 100%, but they can be scaled down if the player wants to do so.
There are two types of Rthro characters: Rthro Normal and Rthro Slender.
*Rthro Normal is achieved by setting Body Type to 100% and Proportions to 0%.
*Rthro Slender is achieved by setting Body Type to 100% and Proportions to 100%.
==Leaks==
Between the time that Anthro was initially announced and when it was released, users have found the main files for Rthro inside Roblox's files. Many videos have surfaced on websites such as YouTube about this. These included faces, or what Roblox called "face projections", legs, textures for bodies, actual bodies, and other unconfirmed avatars.
The original avatars were named Ken (male avatar) and Barb (female avatar) by Roblox, following a similar naming fashion to the male and female Barbie dolls.
===Baseline Model===
Roblox uploaded a model that would become the baseline for all Rthro packages, and can be found in the asset library here.
===Game===
A private group led by (which involves some official Roblox administrators as members) had published a testing game called Avatar Future, which allowed users to experiment with scaling and packages pertaining to Rthro before it went private at the end of September 2018.
==Revisions==
===Enhanced Avatar Scaling Options ===
On May 30, 2018, an announcement was made on the Roblox Developer Forum showcasing two new sliders for the Scale section in the Avatar Editor, which led many to believe Rthro had released due to the ability to scale avatars to more realistic shapes. confirmed this as false on his Twitter, where he states that the scaling were what Rthro evolved into.
=== Unlocked Avatar Scaling Options===
On October 15, 2018, another post was made to the DevForum explaining the next stage of Anthro in full detail, and also referred to it as ‘Rthro’.
==Reception ==
===Pre-release===
====From the community ====
Many Roblox users have criticized the realism of Rthro after it was initially announced. Many arguments suggest that the former avatars were too realistic for Roblox and would only serve to push the platform further towards the uncanny valley due to conflicting with the well-known blocky appearance of avatars. Users also expressed concern that Rthro will replace the more traditional R6 and R15 avatar types, however this was confirmed to be false. There were also fears that the new character style would not be compatible with certain hats and gears, and some also believed that Rthro would encourage online dating.
==== From influencers====
At RDC 2017 and on the Dev Forum, multiple Roblox Developers commented on their dislike for Rthro and made jokes about it. Additionally, several Roblox YouTubers have heavily criticized it, claiming that it would be used by online daters.
===Post-release ===
After the scaling options and first Rthro bundle were released it became controversial quickly, but it was not received as negatively as people had thought. While Rthro bundles are still criticized to this day, they are generally accepted by the community as seldom used in their entirety, and their general usage has primarily come from some players (usually children), trolls, and players who only purchase the bundles for specific parts such as the face or limbs (in a similar vein to the Headless Horseman and Korblox Deathspeaker bundles).
====Scaling====
The scaling receives some criticism regarding funky knees and other things.
====Packages====
The packages have received some criticism for usually looking uncanny. The package itself was reported to have some flaws, where many users had issues with the head in particular as it would often not scale correctly or cause other body proportion issues when worn. Some packages have been praised for being well-made. Roblox has purchased the rights of some avatars from third-party stores like Unity and used them as Rthro avatars which drew some criticism despite Roblox being allowed to do so.
====Animations====
The animation package was also well-received, primarily due to the fact that it is the first free animation pack that Roblox has released.
==== Ban of R6 and R15 in commercial uses ====
On June 23, 2022, Roblox updated their Terms of Use and released a DevForum post that disallows the use of R6 and R15 avatars on off-platform commercial uses without permission from Roblox. However, Rthro is still allowed to be used.
Roblox also said that avatars that are still classified as "R15", but only if the "classic" form is no longer apparent, is allowed.
This change has been criticized by users as a way for Roblox to force users to promote Rthro.
==Trivia ==
*Rthro allows the user to be taller than R6 and standard R15 avatars.
*Rthro characters are able to be used in Roblox Studio, just like any other characters.
*Some of the character models from Fortnite Battle Royale and Mafia III have been used by Roblox to test Rthro, although it is unlikely that they will ever become actual bundles due to potential copyright issues.
*The first user to test the Rthro bundles is , followed by , , FarazTheGreat , , Captain_Rando and kratos3089.
**Rthro bundles were also available early to certain Admins, Interns, DevForum members and Official Roblox STAR Video Creators.
*City Life Man is the first Rthro bundle to be taken offsale. It is unknown why this was done.
*Due to the small sizes of the heads provided in Rthro bundles while using R6 (when compared to existing heads), as well as how many existing accessories do not scale to accommodate such, they have become popular among trolls.
*For a while after it was released, there was a 10-15 minute delay between the time that a bundle was purchased and the time that it took to be available in the user's inventory.
* The Harbinger, Simple Robo and Warchief Mucklug bundles were initially free but given Robux prices a day later, making them the first Rthro bundles to become paid after being free. They were most likely free due to a mistake.
*The tallest character you can get using Rthro requires you to make Proportions 0 and Height 100, Body Type 100.
*Parts from specific Rthro bundles such as Magma Fiend and Triple-Headed Trouble can allow players to become noticeably taller or shorter than the maximum body scaling limits may allow for compared to normal usage. • You can use Magma Fiend to do glitches mostly on popular games Piggy and any other walls that is too short to go on.
