siding orientation changes in perspective and elevation views

[Lighthouse]

Hi,

Here's a strange one-  In my camera views, the siding is horizontal, in the elevation view it's vertical.  In the wall dbx the material appears vertical.  If I create a rotated copy of the material, I get the same issue, the orientation flips 90d depending on the view.

ok, thanks, I'm watching the video to get a better handle on this
