Showcase RectMask2DCulling - optional Culling / Softness, better performance

Custom RectMask2D, that allow to disable Culling / Softness

Available at Github

Problem

Built-in RectMask2D has overhead, that grow linearly with count of active Child UI.Graphic, main reason for this - Culling. When all this UI.Graphic is always visible (if Pooled ScrollRect or Optimized ScrollView Adapter used, for example) - Culling is useless

And you can't disable it

Solution

Inherit from RectMask2D and add flags to disable Culling

Performance

- Profiled at Honor 10X Lite
- 50 child TextMeshPro
- 400 child other various UI.Graphic (UI.Image, UI.RawImage, UI.Text)

- RectMask2D


- RectMask2DCulling , Culling and Softness disabled


- RectMask2DCulling use reflection to get private properties of parent RectMask2D class, and it add performance overhead
