Lr 11 update is causing a major problem with developer profiles. The profiles are not showing up when a preset is applied, or the slider is there but greyed out. As part of a team that has developed many preset collections with custom profiles, this a HUGE problem that needs to get fixed asap!
Hi @johnrellis, thanks so much for sending that over! We had actually been able to get the profiles working on the new (Lr11) version, however our issue is that we want our product to be compatible with earlier versions (Lr10) as well, as many of our users aren't always using the latest update from Adobe. This is what we can't get working...
You can work around this bug by editing Diffusion.xmp in a text editor and changing this line:
crs:HasSettings="True">
to these two lines:
crs:Exposure2012="0.005"
crs:HasSettings="True">
That won't have any noticeable effect on the appearance of the profile, but it will cause the Amount slider to appear.
In LR's Profile browser, right-click the old Diffusion profile and do Delete Profile. Then do File > Import Develop Profiles And Presets to import the modified version.
I think the bug is that LR will only show the Amount slider if there are develop settings in the profile. But this profile contains just one setting, <crs:CircularGradientBasedCorrections>, created by an older version of LR. LR 11 knows how to interpret that setting and convert it to the new mask representation. But the code that determines whether to show the Amount slider evidently doesn't recognize that old setting. Adding crs:Exposure2012="0.005" fools that code into thinking there is at least one setting in the profile and thus it will show the slider.
