5.1

Mobile rendering has undergone some internal changes following improvements made to the rest of the Unreal Engine renderer.

  • New performance improvements and features include mobile GPUScene instancing and culling, Skin Cache, Distance Field support, CSM caching, and the pre-integrated SSS shading model.
  • Mobile Deferred Rendering Mode is a deferred renderer optimized for modern mobile GPU architecture that supports improved lighting and reflection quality and features over that of default Forward Mobile Renderer.(OpenGL ES Experimental)

Notes:

  • OpenGL ES version 3.2 is now required on Android
