RectMask2DCulling

Unity3d | uGUI custom RectMask2D script, that allow to disable Culling / Softness for better performance

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 ( or used, for example) - Culling is useless

And you can't disable it

Solution

Inherite 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
