I often use values under 0 for puffiness on story characters for my game to make their clothes look less blown out, as they still look very large on Robloxian 2.0 characters with the improved fitting.

Pretty great update unfortunately im guessing my invisible avatar trick to make spooky avatars for halloween won’t work anymore with this update but atleast my package ones will be able to finally properly use layered clothing!!

I want to emphasize that I primarily use LC instead of classic clothing, and practically all of my outfits use negative Puffiness values to compress the clothes to fit on my avatar better.
Negative Puffiness values are practically required in order for LC look good on classic avatars. Just look at how bad my shoes look at Puffiness 1.0 (left) compared to Puffiness -0.6 (right). My pants are also at 1.0 and 0 respectively.
Controlling the inflation of multiple stacked layers is not the only use of Puffiness. From my own usage, its main purpose is using negative values to compress single-layer clothes! It seems like Roblox did not take this into account whatsoever, considering how they somehow feel that Puffiness is safe to remove from the engine.
This update is going to destroy all of my avatars. Please make this optional.

The new fitting is good, the feature removals are not.

What about the character Crimson Claw? As you can see in the images there is a problem with the 3D clothing on this character.
In this image you can see the dragon’s tail has completely disappeared
Here is the character without the 3D clothes
And here we can see that there are missing details on the dragon’s tail.
This is a long-standing issue and I don’t know if it will be resolved with this update.
In addition, this character has other problems

I hope this will be fixed soon. Thank you.

Could you please fix the clothing removing geometry. or let us have control over it. some clothes remove the entire neck

There was a bug report filed about this, I’m not sure if the improved fitting algorithm affects HSR at all : HSR System improperly chops off important body geometry
This isn’t related to layered clothing.

I agree, I was looking for someone who would post about this. Some Layered Clothes are too bulky in their default state (including when worn without anything under), and the puffiness value allowed us to shrink them down to make them more skin tight. Please keep this value active, some of us made good use of this for outfits, and without it we’ll be stuck with a lot of clothes that are too bulky to look good.
[EDIT] I decided to take a snapshot with some examples. The most noticeable change can be seen on the heavy armor. With Puffiness set to -0.4, it looks like an agile mobile suit, in the default state it looks too bulky to even make sense to move with. The kimono inflates a bit around the waist/chest, and the black coat just becomes a balloon. (That happens even if I remove the pants underneath too, just not as bad)

Has this been rolled out already? I want to see if I can finally create the avatar I’ve wanted to have.

This was said to roll out around the end of March, and it’s now April 3rd.
I still don’t know if these changes are good or not… I really hope this can be made optional somehow, because I’m really worried about all of this.
The new algorithm is nice.
The issue of flaring near the hands and feet can be annoying and I’m glad that’s being fixed.
The bulkiness of multiple layers can already be solved by setting the Puffiness of the top layer to 0, but setting Puffiness is a very manual thing that doesn’t even have a UI in the default avatar editor. Most people don’t even know it exists. The only way you can set Puffiness is by manually calling an avatar API or by using third-party tools. This new algorithm would essentially make this process completely automatic so that you wouldn’t have to worry about that anymore.
But if Puffiness already works, wouldn’t it make more sense to just change the default Puffiness value to 0 instead of 1? That would fix the bulkiness of multi-layered outfits for everyone, without ruining any existing configurations.
For reference, here’s the current API documentation for Puffiness:
Controls how much underlying clothing items inflate the current clothing item.
Valid range is -1 to 1. A value of -1 compresses the clothing, body, and all underlying layers such that the clothing itself takes the shape of the body. A value of 0 makes the clothing item fit as if it was the only piece of clothing being worn, compressing all underlying layers. A value of 1 (default) never compresses anything and infinitely inflates over underlying clothing items.
And the new algorithm does not seem to take into account the idea of using negative Puffiness values to further compress your clothes, beyond just deflating multiple stacked layers. Also, in some cases you might actually want to keep multiple layers fully-inflated as mentioned in some other comments here.
I heavily rely on negative Puffiness values for my outfits, so removing it would probably ruin all of my avatars. The only way I could realistically keep my avatar with this change is if I design some custom body to preserve the old fit of my clothes, but that’s just unnecessarily complicated and not something that I or most other users would even know how to do.
While not as significant, I’m also a little worried about the issue of flaring near hands and feet being fixed, because it’s possible that some outfit out there actually relies on the old behavior. It feels like a good change, but you never know.
It just feels too hard to touch LC fitting without affecting any existing outfits, especially since LC has been available for three years now. Really hoping the team can find a solution.

Has this been implemented yet? Its been a week since April started but i haven’t noticed any changes to the clothing yet.

This is something that I would prefer over deflating all avatars by default. I did send out one of my avatars that needs the puffiness to be set to max, so I hope that it stays. I do think that Roblox should implement a first-party way; similar to how a lot of third-party solutions do it
My main Roblox avatar is a perfect example
It just doesn’t make sense to be forced to make a custom body just to be able to resolve this, I do agree
I also hope that these issues can be resolved. I doubt that creators want to fix hundreds of their assets. Developers already suffer from the issue of things breaking from updates and I don’t want that plague to be spread to the avatar marketplace

Any updates on this releasing?

Well, this change just appeared as “Pending” in the latest release notes. Is this really about to happen?
I know I keep restating myself but I’m still REALLY worried about this, because this might ruin all of the avatars I’ve made over the last three years.

It is concerning that they still want to proceed with deprecating and essentially removing them. Only hoping that “pending” is not going into live and is canned
I wonder if the avatar I sent to Roblox for testing was even used to address the issues. It really seems like they just didn’t bother ensuring the backwards compatibility of specifically designed outfits, even after so much was said about that as a concern
We should be allowed to bulk up avatars to our liking and shape them to our own. I don’t like that being limited

I sent them a few avatars as well after being DM’d by an engineer.
This will be so disappointing if this change actually goes through. What’s the point in actually trying to be creative with new avatar technology if Roblox can just suddenly decide to break everything you’ve designed and spent Robux on over the last few years? I might as well just go back to using the block body with classic clothing…

Also before this its was something necessary to use skinny bodies to prevent it
Technically you could use negative Puffiness values to compress the item if you knew what you were doing. Also, this change is not going to affect single-layer outfits at all. I feel like most people here are missing the point. If you’re wearing a t-shirt and nothing else it is going to look the exact same. The shirt is going to stay just as bulky as it was before.
This change is only going to compress multi-layered outfits, which was the entire reason Puffiness existed in the first place. Notice how in all of the examples provided by the OP the characters are wearing multiple layers (jacket over shirt).
And since Puffiness is being removed, it will be impossible to compress single-layer outfits now.
