Questions about Generator: mesh/objects within spline, snap to control point

[dartboard]

Hi Aka,

Thanks for the helpful reply! I have a couple more questions:
1) I'm using similar shapes with varying heights to create a path using Variable Mix Shapes, but the areas that are shorter does not look accurate to the shape I have created. Is there a way to make sure the mesh stays true to the shapes I'm using?
2) Is it possible to change materials or apply decals midway down a mesh I've generated with a spline?

Thanks again!
