I am having trouble on how to show the brick pattern on my 3d views. Some shows some do not, only the shade color. i am exporting or printng to pdf these 3d images under consistent shade mode no shadows. i tried flipping wall orientations, didn't work. Apparently when v viewing afar the patterns do not show, when zooming in to the view they show up. but the savifn the current 3d viewing with the patterns partly showing yields the same output prints. Has anyone encounter this problem?
