Google Chrome WebGL Shader Compile Linker Error, Uniforms with the same name but different type/precision
google-chrome, precision, shader, uniform, webgl
Solution
I resolved this by adding `precision mediump float;` to my vertex shaders to match the precision defined for their fragment counterparts.
Problem
Uniforms with the same name but different type/precision This is what i am getting when compiling the shaders, with only the latest Chrome on Windows. nothing else Looking at the http://www.cocos2d-x.org/forums/19/topics/39063?r=39258 and https://code.google.com/p/chromium/issues/detail?id=309527 I tried to add both highp for both of the following, and it doesnt help either. VShader : ``` "attribute vec3 a_position; \n" "attribute vec3 a_normal; \n" "attribute vec2 a_texture; \n" "uniform mat4 u_mvpMatrix; \n" "uniform mat3 u_normalMatrix; \n" "uniform vec4 u_lightDir; \n" "uniform lowp int u_eT; \n" "uniform lowp int u_eL; \n" "uniform vec4 u_colormul; \n" "varying float v_cf; \n" "varying vec2 v_t; \n" ``` F Shader ``` "precision mediump float; \n" "uniform vec4 u_color; \n" "uniform lowp int u_eT; \n" "uniform sampler2D u_texture0; \n" "uniform vec4 u_colormul; \n" "varying float v_cf; \n" "varying vec2 v_t; \n" ``` Early response is highly appreciated Thank you
