Question Probuilder API - combine mesh textures

How I can stretch the texture on the combined mesh instead of having the texture on every single cube that the mesh was combined of???

So say I combined 5x3 grid of cubes to a single mesh (wall) and I want a texture to be applied on the whole ONE wall, not the all separate cubes that make the single mesh. Currently, I can see 15 separated textures on the combined mesh.

 

Ahh found IT!.

Code (CSharp):

1.       mesh.faces.ToList().ForEach(face=> face.uv = AutoUnwrapSettings.stretch);
2.  

This solves my problem
