I only tried this on one setting. Was playing around and wanted to see what the adaptive layer height would do in one of my builds.
I grouped all the processes and then checked the adaptive layer height in one process. It only changed it in that process. By V4 process grouping workflow it should have changed that setting in all processes. Have not explored the extent of this.
UPDATE - I did change something else in a process group and it updated in all processes ... might be something specific with adaptive layer height.
