i'm quite new to this openGL ES and EGL stuff.
at the moment im porting a win32 openGL app to openGL ES.
my only problem at the moment is that i can only get 4 bit (16 steps) of alpha blending.
so my fading out textures look realy ugly.
in the openGL version i had a smooth transition, in my GLES/EGL port the fade out is stepped.
is there a EGL or GL ES flag to increase the resolution of the available alpha chanel?

many thanks!
