Material Tiling Switches from Vertical to Horizontal

Hi there. I’m attempting to make a Vinyl Siding material. I put the material on my object, that is all one mesh and when I put it on, the East/West facing walls change the material vertical, and the south/west walls have the material horizontal. Its all one mesh, and all one material… Im confused whats going on. Any help would be appreciated! Thanks!

You need to go back to your 3d program of choice, and rotate the UV island of that wall 90 degrees so its aligned properly.

Luos, you sir are a savior! Very new to 3ds Max and it shows. Thank you very much!!
