Menu overview

The menu is added inside the VirtualLens 2 menu. With the English prefab it looks like this.

VirtualLens2
└ Nakao Filter
   ├ Mist Filter
   ├ Cross Streak
   ├ Directional Blur
   ├ Iris Filter
   ├ Color Grading
   ├ Spiral Grid
   ├ Watermark
   └ More
      ├ Debug Monitor
      └ Reset

Turn each filter on with "Enable". Settings are saved and stay the same the next time you use the avatar.

On avatars that use the VirtualLens 2 Quick Calls, the menu would go over the limit, so Nakao Filter moves into "More" automatically.

Slider values

This documentation gives slider (radial) values as the 0 to 100% shown in the menu.
