We got problem with ETC2 compression for Android devices.
Android devices we are testing have OpenGL 3.2 so they support ETC2 definitely.
We use Texture Packer for building our sprite sheets.
Sprite sheet size is 4096x4096 and compression is set ETC2 + Alpha.
On Iphone devices that config works like a charm. But on Android it just draws black screen or some corrupted unknown squares.
If I remove Alpha from settings Android renders correct (with black colour on transparent pixels)
Did anyone met such issue ever?
Thanks for support, David
