You can Set the Basepart’s Of the Character’s Color.
Try This Script in ServerScriptService.
This should work Smoothly, I just Tested it on A Baseplate.
game.Players.PlayerAdded:Connect(function(Player)
Player.CharacterAdded:Connect(function(Character)
local function SetColor(BasePart)
if not BasePart:IsA("BasePart") then return end
BasePart.Color=Color3.fromRGB(0,0,0) -- Black Color
end
for i, v in pairs(Character:GetChildren()) do SetColor(v) end
Character.ChildAdded:Connect(SetColor)
end)
end)
