I have HDP 2020 and I'm trying to rotate tongue and groove ceiling materials 90 degrees from how they appear. Following the online tutorials, I selected the object and used the 'Adjust Material Definition' button to enter into the display box. I changed the angle on the material 90 degrees and the small display box reflected the change, just like the tutorial. I then clicked OK, which took me back to the 'perspective full overview' screen I started on and...no change. I repeated the process with the same result (definition of insanity?). Rats!
Any suggestions? I've tried other materials, again, following the tutorial, and get the same result. Help please!
