I am encountering issues with a hillshade layer beneath two geologic maps at 55% transparency disappearing when printing. The whole map exports to PDF without issue, but when printing from ArcGIS Pro itself, only the geologic map layers appear. The colors of the geomaps upon printing are more pale/desaturated than their original colors, suggesting that the transparency is still working and that the hillshade is just disappearing.
I have tried adjusting the "In Beyond" and "Out Beyond" for all three layers to a range that includes my desired scale, and to "<None>", but I have had no luck.
Any help would be greatly appreciated!
