I generate that kind of mesh during runtime to display the path to follow to a target (think at something like the path your GPS shows you when you are travelling):
I need to reduce the displayed path going from one end to the other to simulate the travel the player did. What can I do to achieve such effect?
I can think about vertex modifications at runtime directly from a Monobehaviour class, or a shader(?). Are there any other (smarter?) moves to do here? Is Vertex modification the wiser choice for that kind of case?
