Description

"Brightness (exposure)" slider doesn't work on Bug Island 2

Reproduction steps

1. Log in with the ExtraFPS 7.1.11.11750364439 viewer (https://releasenotes.secondlife.com/viewer/7.1.11.11750364439.html)
2. Visit http://maps.secondlife.com/secondlife/Bug%20Island%202/111/30/23
3. Ensure World > Environment is set to Use Shared Environment
4. Open Preferences > Graphics and move the "Brightness (exposure)" slider back and forth.

Observed: Nothing happens on ExtraFPS 7.1.11.11750364439. Personal lighting > Reflection Probe Ambiance = 0.00

Expected; The environment should get darker and lighter, as in DeltaFPS 7.1.10.10800445603. Personal lighting > Reflection Probe Ambiance = 0.01

Note 1: This may be due to #2632 but I'm not sure.
Note 2: Is the real issue that Personal lighting at that location shows Reflection Probe Ambiance = 0.01 in DeltaFPS and 0.00 in ExtraFPS?

[kylelinden]

DeltaFPS had auto adjust so the 0.01 data was accurate.
ExtraFPS now does not have auto adjust so 0.00 is now accurate.

Failed QA.

Now, when scrolling the "Brightness (exposure)" slider back and forth, the environment changes accordingly.
But when changing other parameters(the Tone Mapping Mix, the Tone Mapper between Khronos Neutral and ACES ), the changes are still not visually visible.

Verified on the Second Life Release 7.1.11.12041172537 (64bit) on Win10/OSX on http://maps.secondlife.com/secondlife/Bug%20Island%202/111/30/23 location in the scope of https://github.com/secondlife/iqa/issues/401.

[Geenz]

Tone mapping is not supported on legacy skies.

[AtlasLinden]

As given by Geenz's comment, Tone Mapper and Exposure settings will no longer work on legacy skies (skies with Reflection Probe Ambiance = 0).

With newly created skies this is verified. However, on multiple regions that previously had a legacy sky applied (including Bug Island and multiple randomly selected mainland regions), the exposure setting is still making changes as given by Valeriia's comment above.
The Tonemapper settings are not visible (also mentioned in above comment)

Gray out the slider when not available.
