Question by kosted · Dec 07, 2017 at 02:40 PM · shaderiosxcode

IOS : extension 'GL_EXT_frag_depth' is not supported

Hi Unity community. I export my project on Mac to deploy on IOS, but i'm facing a terrible issue. The game crashes, after splash screen, and in the log I have this error :

 -------- Shader compilation failed
 #version 100
 #extension GL_EXT_frag_depth : enable
 precision highp float;
 uniform sampler2D _MainTex;
 uniform highp sampler2D _DepthTex;
 uniform highp vec4 _Color;
 varying highp vec2 xlv_TEXCOORD0;
 void main ()
 {
   lowp vec4 tmpvar_1;
   tmpvar_1 = (texture2D (_MainTex, xlv_TEXCOORD0) * _Color);
   gl_FragDepthEXT = texture2D (_DepthTex, xlv_TEXCOORD0).x;
   gl_FragData[0] = tmpvar_1;
 }
 -------- failed compiling:
 fragment evaluation shader

I tried many solution by setting Depth normals into "no support" for example, but still have the same issue. How could I resolve it please ?

@lexi89puzzle Try using Metal from Autographics API setting under build settings. Remove OpenGL form the list
