I made a bunch of standartized tests. Here are some of them. At this point I really consider Height maps in R7 to be a downgrade. I get MUCH, MUCH better results when I keep them OFF at all times. It applies to any medium: oil, watercolor, pastels..
I expected this technology to help enhance my skills not worsen them. I'm not sure it's fixable even.
Don't get me wrong, there are good additions in R7. But devs advertized their software with this HM technology telling how realistic it woul look. Results prove the opposite.
Same brush, same pressure applied.
