I have a terrain I have been fine-tuning for some time. I have edited this terrain at least a dozen times prior, without issues. Added Gaia and AQUAS content. Made more changes. No problem. But now suddenly I am unable to set opacity when smoothing or attempting to Raise/Lower Terrain. So, I can no longer change it. Any suggestions? Currently using 2017.1.1f1.
I found this in the archives. Had to reset my layout and it started working again. Apparently this is a long-standing, lingering bug.
