It would be nice to edit the skin wiki info to add a warning about capes, because since 5.0 the feature has been removed (I just created a skin and struggled for a LONG time before reading the whole changelog, and figure it out).

Or put back the functionality, which I find nice because many more people can see the cape (the "Capes" mod, used to display a lot of different capes, deactivates "minecraftcapes.net" capes by default). 🙂

that's a lot of capes...

Just an image of the cape (with an old version of the mod)

My Skin :

Ah that should have been corrected I'll look into it, which cape mod are you referring?

It's somewhat unlikely I'll re add the capes but I might do it when I do some of the planned changes to the skin feature system

I'm referring to this mod https://www.modrinth.com/mod/capes, which is widely used (description: A Fabric and Forge mod that lets you use capes from Optifine, LabyMod, and the MinecraftCapes Mod),
but by default only optifine cape are enabled
