This tiny addon alters the games internal settings to increase the maximum values for AoE Brightness as well as Target Glow Thickness and Intensity. It was originally developed as private addon for VespersPlea who donated gold and asked for this specific feature.
FYI I've tried to alter other internal settings (eg.: Field of View) too but while it's possible to change the values, it does not have any effect in the game which leads to the conclusion that certain values are internally capped.
LATEST CHANGES
Version 1.0.1 (2021/06/04)
- Added Target Glow Thickness & Intensity
AOE BRIGHTNESS
These settings are accountwide and found under Gameplay -> Combat.
The addon increased the maximum value for AoE Brightness by a factor of 10. While this might be useful in raid situations with tightly stacked groups where recognizing AoEs can be tricky, it can also get quite annoying in situations with lots of huge AoEs (eg.: Cyrodiil with Caltrops, Meatbags, etc.)
TARGET GLOW THICKNESS & INTENSITY
These settings are character specific and found under Nameplates -> Indicators.
The addon increased the maximum value for Target Glow Thickness and Intensity by a factor of 20. This is mostly useful in situations with multiple enemies like trashpacks or PvP where it's important to focus a specific target.
