I want to make the beginning and end of a mesh translucent.

[yanke]

I am looking for a way to apply a translucent gradient to the beginning and end of a mesh created with Curvy Spline.
If there is some convenient way to do this on the library side, please let me know.
(Currently, I am trying to implement this by creating two GameObjects that are different from the mesh and overlapping them at the beginning and end).

thanks
