"Stretch to end" for CreateGameObjects

[_Aka_]

About issue 1: The Deform Mesh module produces V(irtual) Meshes that, connected to a Create Mesh module, will create a game object containing the mesh, and if the option is set, will also produce the correct associated mesh collider. Have you tried using the Deform Mesh module for your wall? Since the wall is a straight line, there should not be any deformation other than the stretching. If you already have tried this solution and it doesn't work, please send me a reproduction case and I will look into it.
Thanks and have a nice day
