I was able to subscribe but I do not know how to extract the files to use the MSF.

Colouring can be done with using either a series of .vtf files for each official mii colour, or a single white .vtf file with various .vmt for each colour, via the $color2 command. The later will probably be easier.

3D features like head, hair and noses can be .smd files that can be compiled.

Face textures... That be more difficult. I know in Mii Maker players can move features in manner of ways so how that can be recreated I don't know. I can imagine position and scale could probably be listed on the mii .qc file but dunno if possible to pull of. I have a rough idea but I'll need to look into it.

As for how to write a .bat compiler I have no idea... but I could probably figure out half of things from Sonic Forces Avatar mod.

That would probably work, but I don't know how I would go about doing colors for skin and hair. Or the custom face textures.

From what I understand how the Sonic Forces Avatar mod work, it has all the parts as .smd files in various folders. And on a separate .qc file you can list all the $model parts you want the Avatar to have as well as things to $include. Then you place the .qc file onto a .bat file that compiles it.

Of course, understanding how it works is different from knowing how it works, but maybe you could talk to the creator of the Avatar Mania mod on how he did it.

Either way, they can have default mii-bodies but easy-headhacking to the SSBU mii bodies.

Nope, that’s a lot of work outside of my currently skill set. I have been thinking of making an updated guided tailored for my Mii bodies on how to create your own Mii heads, haven’t gotten around to it.

Is there like... I dunno, like some sort of "SFM Mii Compiler" out there?
Like, I know that Sonic Forces avatars were made into a SFM compiler https://www.youtube.com/watch?v=C3NiRoJnqhk just wondering if there was something of the like for Mii's, especially to headhack for these SSB models.

When i Spawn the head its an Error sighn.
How do i fix that?

Retexture it in photoshop or gimp or something

Any plans to allow changing the hair color I am looking for this but I want to have the hair be brown

No plans for that, I did have plans to make a guide on how to get a model of your own Mii but that hasn’t gotten anywhere. There are too many costumes for Miis for me to tackle right now anyway.

So.. Umm... Would you make maybe like a mii model that can be customized? In short is like... Mii maker in SFM or S2FM

Spawn in a head and lock it onto any of the bodies like you would a tf2 cosmetic

How do add the Head?

“No one plays him tho”
“Sans for the Mii”
