Migrating Heads and Accessories to be MeshParts

[formy2kids (Infernus)]

The only other hats with scripts that aren’t exclusive to admins are the sound hats, and they do not reference the SpecialMesh in the hat, so this update wouldn’t break those scripts. This would affect the Rbadam’s Smokestack specifically due to the fact that it references the SpecialMesh in the hat. However, this could easily be fixed with some simple if thens, so the hat can work with the new update and with the original SpecialMesh in a part.

The only thing that must be added to fix the hat is another part in the hat to blow the smoke properly. Using a MeshPart for the hat makes the smoke come out of the entire hat rather than just the middle as it does currently. Also, MeshId cannot be edited with the script if the hat is a MeshPart, so some of the textures would look broken since they are on the wrong mesh. This just makes it stupidly complicated, as there would now have to be 2 MeshParts, one with the new mesh’s MeshId, and one with the standard one. One of them is visible depending on the event, for example, the birthday event uses the new mesh, and no event uses the standard mesh. This is the best solution I could think of.

This is a big update, I’m tired of particles surrounding the whole player head box rather than the circle. Thanks for this update.

[Dogutsune (Dogu)]

I want to clarify few things though.

1. There’s hats with scripts. This one for example uses SpecialMesh in it’s script to alter it’s own mesh.
   You might want to check some scripted hats, redo their scripts as well.
   Example: Rbadam's Smokestack Top Hat - Roblox

2. There’s some hats with VertexColor. That means MeshParts require Color3 property.
   Example: Brainfreeze - Roblox

Wouldn’t it break those hats?

[Dogutsune (Dogu)]

I believe attachment could fix the issue!
Just put particle inside of it. There might be no offset variety like for part though.

[bt5191 (btt)]

I’m excited for this change, this also means exploiters will in future, be unable to delete the meshes in their accessories which means plenty of exploits which do things like make blocks won’t work anymore.

[Dogutsune (Dogu)]

I did a fix to address this future change.
Was fun!

[formy2kids (Infernus)]

You’re right, an attachment would probably fix the issue there. As for the changing mesh issue, that would still require 2 meshparts, as you can’t change the MeshId of a meshpart in game for some reason still. And yes, we 100% need Color3 in meshparts, I have wanted this for so long.

Adjusting the Color3 of a MeshPart Texture

As a Roblox developer, it is currently too hard to alter the colour of a texture on a MeshPart, meaning a developer would have to create alternate textures just to differentiate a texture’s colour appearance. One way to tackle this would be to add similar Color3 properties to MeshParts’ textures, making it increasingly easier to modify meshes with ease on the Roblox engine. An example of this would be to add the Color3 property (similar to a decal or texture) on a MeshPart texture property: [i…

[Dogutsune (Dogu)]

Yeah, that’s why I did a hacky fix for said hat out of pure boredom.

Migrating Heads and Accessories to be MeshParts

I did a fix to address this future change. Was fun!

@Noble_Draconian

Is there any chance that package ‘heads’ will be converted from hat accessories to actual head meshes? E.g. the crimson claw package’s head is currently a hat accessory. Will it be converted to a head mesh?
If this were the case, already existing packages could make use of the upcoming “facial animations” feature.

@CodeWriter Dev. reached out, Can you answer?

[Maximum_ADHD]

I noticed in this week’s update that characterR15V4.rbxm was added with a MeshPart head, but there seems to be an issue with the normal mapping seams around the face.

I’m sure this is known about, but I just wanted to post it here in case it was overlooked.

[DeathLilian (Alyssa)]

Is that R15V4.rbxm available to obtain it? also are these head on dummy models from the plugins will be changed to be a MeshParts?

[CodeWriter]

This will be fixed once the new code is enabled.

[Clueless_Brick]

What’s the update on the migration of MeshParts?

[ShutzCh (Shutz)]

What’s also the update on the addition of texture coloring for meshparts? I feel like this is a needed addition considering Roblox is embracing meshparts more and more as time goes.

@Osyris

Assuming everything goes well, within the next couple of weeks for heads, and soon after that for accessories.

Any updates on issues that are causing the massive delay?

[Osyris]

We’ve decided to ship MeshPart heads and accessories at the same time instead of as two separate releases. Should reduce complexity. Accessories took much longer because we had to convert the entire existing catalog of accessories (including UGC uploads).

[builderboy256]

This update seems to break acessories still using the deprecated ‘Hat’ instance

for example this: Ceremonial Guard of the Archduke of the Federation - Roblox now refuses to load in game

[Maxwell_Edison]

This feels like a weird setting to be put in Workspace’s properties. Feels like it should be in StarterPlayer properties or something, since it’s something that really only directly affects which type loads in when players join. Really nothing to do with the general game/workspace

[acreol]

It breaks this accessory, maybe because the SpecialMesh is called “SpecialMesh” not “Mesh”
