For some reason my shader that is based on the waterdrop ripple shader (https://forum.thegamecreators.com/thread/215563) that can be found in this forum, won't run on iPhone (iPhone 13, iPhone SE (8?) tested, both fail). It runs on Android, Windows and OSX just fine. Obviously there's something in the shader that won't initialize on iOS. Perhaps one of you has run into the same issue of trying to get shaders to run on iOS?
It won't be the end of the world, as I need to implement a fallback solution anyway for older phones. But for the water ripple shader really being so basic, I don't really understand why it won't run.
Any experiences with iOS and shaders?
