QB vms_multichar

In vms_multichars/config/config.lua set Config.SkinManager to rcore_clothing

In vms_multichars/client/main.lua find exports['illenium-appearance']:setPedAppearance(PlayerPedId(), data)

and replace it with the following code (should be two occurences)

        exports['illenium-appearance']:setPedAppearance(PlayerPedId(), data)
    elseif Config.SkinManager == "rcore_clothing" then
        exports.rcore_clothing:setPedSkin(PlayerPedId(), data)

In vms_multichars/server/main.lua find QBCore.Functions.CreateCallback("vms_multichars:getSkin", function(_, cb, cid)

and put the following code right after this line

    if Config.SkinManager == 'rcore_clothing' then
        local skin = exports.rcore_clothing:getSkinByIdentifier(cid)
        if skin then
            cb(skin.ped_model, json.encode(skin.skin))
        else
            cb(nil)
        end
        return
    end
