I do a some research to use ATF textures in my app, and I stuck on problem with Android devices.
On my devices Samsung Galaxy Tab S 10.5, Nexus 7 and OnePlus One, ATF textures generated with default parameters "png2atf -c -i texture.png -o texture.atf" was not visible (shows empy space or latest properly loaded texture).
On android devices with support of OpenGl ES 3.0, textures with single ETC2 format also doesn't work.
On iOS and Windows this doesn't occure, everything works fine.
When I generate ATF with png2atf -c d,e,p without ETC2 everything works fine.
Texture size 256x256 with all mipmaps, AIR 20, starling 1.7, Feathers 2.3.0, renderMode direct.
Any Idea what is wrong?
