Can materials be applied to all 3D objects? I have been able to apply materials to every 3D object in my project but one. If it matters, I created this object (a half-cup of sorts) from a section plane cutting a full "cup" in half vertically. I can add materials onto the original cup, however. Please see the snip attached. No matter what techniques I use, I can add no material on this object. Please check out the snip of the specific object and my project attached.
Thanks in advance!
