When provided a list of ColorId’s, :SetColorAlpha does not actually update the transparency at the designated vertices.
A test place will be provided in the private content section. The script that generates and modifies the editable mesh is called “Wave”, located under ReplicatedStorage>Services>WaveService.
Expected behavior
From bottom to top, a gradient from transparency = 1 to transparency = 0 should be visible on the mesh.
