CYOS bugs


Recommended Posts


1. cant save Cyos 

2. this shader result is not corrct in Cyos but have correct result in PG

*notic this line in vertex shader :  vNormal = normal; 

if you remove that shader render correctly


precision highp float;

// Attributes
attribute vec3 position;
attribute vec3 normal;
attribute vec2 uv;

// Uniforms
uniform mat4 worldViewProjection;

// Varying
varying vec2 vUV;
varying vec4 vPosition;
varying vec3 vNormal;

void main(void) {
      vec4 p = vec4( position, 1. );

    vPosition = p;
    vNormal = normal; 
    vUV = uv;

    gl_Position = worldViewProjection * p;


precision highp float;

varying vec2 vUV;

varying vec4 vPosition;
varying vec3 vNormal;

uniform sampler2D textureSampler;

void main(void) {
    gl_FragColor = texture2D(textureSampler, vUV);
