straight alpha issues on Android/iOS

NinjaDog

i have 100+ spine resources in my project,most works fine both on PC and Mobile(Android/iOS)
all of them has correct alpha on PC,but a few spines didn't work right on the mobile,seems like the 'STRAIGHT_ALPHA_INPUT' disabled,but i'm ensure the 'STRAIGHT_ALPHA_INPUT' keyword already been enabled,because i've checked materials manually
i have no idea

What runtime are you using? Even then it's hard for us to say what's going on, except to be sure you are exporting without PMA and are rendering without PMA and to make sure nothing in the asset pipeline is applying PMA (that happens a lot with iOS/Xcode).

Thanks ,I've already fixed it,i modified code to enable PMA always .
