Humanoid:ApplyDescription() returning an error

1XPotato_X1 · November 13, 2023, 7:53pm

Quick Context

I’m making a commission which is an inspect tool, here you could wear/unwear things from your avatar, but the Humanoid:ApplyDescription() is returning this error:
Humanoid::ApplyDescription() The current HumanoidDescription does not match the assets currently applied to the character. Did you edit the character?

Useful Information

ApplyDescription() is being called from the Client.
LocalScript is located under a ScreenGui.

What i’m trying to achieve:

Basically just buttons that unwears your equipped accessory, which updates your avatar in the viewportframe.

Ps: This is my first time trying to work with HumanoidDescription, it really seems pretty confusing to work with.

If you need more information about what i’m trying to achieve, please, make sure to be clear in what info you need specifically, i’ll try my best to explain it clearly to you.

Edit: If you have any tips of optimization and good practice related to this code, please tell me^^

Edit2: The error isn’t happening anymore, i modified the script a bit and now i’m parenting the newHd to the humanoid and stuff. The humanoid description is being modified, however it isn’t applying to the model, in the properties i can see clearly that the humanoid description is in fact being modified, i just need to apply it, which isn’t happening. (No error is being returned anymore, basically i do not know how to solve this problem.)

Arkston · November 13, 2023, 8:41pm

This might not be very helpful but I think the issue lies somewhere within how you make the new humanoid description, because the error suggests there is an issue with the humanoiddescription you’re trying to apply.

1XPotato_X1 · November 13, 2023, 8:45pm

Yeah, i tried something new right now, the error dissappeared but it stills not update the player avatar, even tho the humanoid description is in fact being modified, i just need to find a way to apply this humanoid description to the model.

1XPotato_X1 · November 15, 2023, 3:47am

bumping this post because i really need help

Fizzitix · November 15, 2023, 4:15am

Try using the HumanoidDescription that already exists under the Humanoid instead of creating a new one.

local function changeAvatar(hum, properties)
    local description = hum:WaitForChild("HumanoidDescription")

    for property, value in pairs(properties) do
        description[property] = value
    end
    
    hum:ApplyDescription(description)
end

1XPotato_X1 · November 16, 2023, 7:29pm

Just did that and it doesnt works, i’m surprised that there isn’t literally ANY error, it just doesnt works, i’m about to make a workaround if i dont find any way to fix that.

1XPotato_X1 · November 21, 2023, 3:39pm

Problem Solved, used set accessories and :gsub aswell to filter some stuff.
