iOS/pc : doesn't render the same.

Hello,

I'm currently working on a shader and, while it's close to completion on PC, it's really nothing alike on my iOS 9 device. I believe the main cause of that "bug" is that I don't handle random in shaders correctly; I can remember an old post on that subject, but can't find it. Could anyone point it to me?

It's certainly caused by bad initialization of gl_FragColor for Mac. Instead of gl_FragColor=color ; you must initialize it correctly on IOS

like gl_FragColor=vec4(vec3(color),1.0);

Hope this can help ..

I'll have a try at this, and report, thanks!
