Automatic tiling

Hi, dear Ue4 Developers!

I have an issue, my mesh is have one material, i need to repeat them individualy.
As example:

At the first screenshot, i have a normal texture with normal displaying, but at the second screenshot, i have a streched texture, how can i fix that?

All walls is the single mesh, i can’t split them.

You can use world aligned texturing or create material instances for different sizes of walls

Thank’s for the help!
