Right now I'm trying to create a part that gets heavier overtime by increasing its density and I want to do this using PhysicsProperties but it doesn't seem I'm able to tween PhysicsProperties is there a way to do this?
game:GetService("TweenService"):Create(workspace.Part,TweenInfo.new(1),{CustomPhysicalProperties=PhysicalProperties.new(100, 0.48, 0.2, 1, 1)}):Play()
Here is what I'm attempting to do.
