Well , Most players now had packages. They didn't use the default one. I want to force all the players on my game that uses other than the default one to the default one.
Hope you understand my english XD
P.S - I searched on the internet for hours,but I can't find a solution :(
---EDIT---
Here's an example . *Player 1 using the R15 but with "Man Left Arm" Equipped *When Player 1 joined my game ,the Player would see his own arm a "Man Left Arm" *How do I make the server change the Player 1 arm to Default R15 morph? (Block R15 Rig)
Okay, so here's the real answer you seem looking for. So first you got to force them to have R15, so you will have to go to the game settings, which is in Home tab when you open roblox studio, https://gyazo.com/8e49e931f686c741eaa72a172118110e . The next step is to check this box, https://gyazo.com/8e49e931f686c741eaa72a172118110e and disable any size changes. Now to scripting part. You have to make a serverside script. Inside that script put this
game.Players.PlayerAdded:connect(function(player) player.CanLoadCharacterAppearance = false end)
and then it will just make it blank.
Second answer. Do all the steps above until to the scripting part. The second answer is to make a custom character, which requires no scripting, but will make all the players look the same. By custom I mean taking a r15 character, link here: https://www.roblox.com/catalog/01549049639/redirect . So how do I make it customized? It's pretty simple. First off all just copy shirts link you want and then add a shirt to the character, and to pants it's pretty much same but it's just pants. Now you just have to rename the character to "StarterCharacter" and add it in StarterPlayer. Now you're done.
I think the game avatar settings are what you're looking for, I'm pretty sure the "Avatar Body Type " option in your game's configuration is what forces the players to use the default no-package look.
Roblox.com -> Develop -> Configure Game -> Avatar Settings.
This is what you are looking for.

Just a heads up roblox doesn't really support this is they don't care if they tweak it or remove it. SO you might see your self tweaking your script a lot. This is the only thing that can help you from what you are asking.
