Object's mass doesnt change despite massless value being on

No this is not a text bug, the object actually still has mass ingame

Oh and lowering density doesn’t work don’t bother suggesting it, i need completely 0 mass.

A part by itself can’t be massless, it has to be welded into another unanchored part to become massless.

Lowering density is your closest option. Weld it to a really small part and setting that density to the lowest value. That’ll make the mass so small due to the size that its effectively zero

What about objects that cant be welded otherwise they will break, like objects that are connected to hinges? This is such a stupid rule

local part = script.Parent  -- Assuming this script is a child of the part

-- Function to print the mass of the part and its assembly root part
local function printMass()
    local mass = part:GetMass()
    local assemblyMass = part.AssemblyMass
    print("Part Mass: " .. mass)
    print("Assembly Mass: " .. assemblyMass)
end

-- Setting the part to massless
part.Massless = true

-- Print the mass after setting it to massless
printMass()

-- Wait for a short duration to see if there's any change over time
wait(1)

-- Print the mass again to check if it remains consistent
printMass()

Maybe that part will work with the script you need to add

I had a similar issue when connecting moving rotors for a helicopter, here’s what i did:

the rotor mesh part is massless and welded to the middle part which in turn is connected to the base with a hinge, the middle part has a really small size so when setting the density to 0.01 the mass becomes zero.

For some reason if its massless it flings
