Mass physics density question

[OhMyCrazyScript]

Hello! Im a bit confused, its a rope pulling game where you just pull a square with friction set and some density… for the players: i made all of the baseparts massless except the humanoid root part bc you can’t move), and welded a part with custom density like “4” in this case, “strenght 4” (the root part has 0.01 density so we have the same mass)
Here is the weird thing, my friend can pull an item and I cannot, its supossed that we have the exact same mass right?, some physics expert can help us with this? im missing something thankyou

The critical factor is what has NetworkOwnership of the part. If the part is owned by a different player or the server theres a good chance you wont be able to pull it no matter what.

yea the owner is the player in this case
