Forums - Adreno 330 GLES3 gl_InstanceID does not work

Dear colleagues,

could you please check the following issue:

I`m trying to make instance rendering on adreno 330

( i actually tried Nexus 5 with Andoird 4.4.4, Galaxy S5 G900F, LG G2 ) and it fails

to use gl_InstanceID with the following shader

#version 300 es
layout(location = 0) in vec4 av4position;
layout(location = 1) in vec3 av3normal;
layout(location = 2) in vec3 av3uvw;

out vec3 vNormal;
out vec3 vViewVec;
out vec3 UVW;

uniform mat4 Model;
uniform mat4 MShip[2];

 
layout(std140) uniform GShaderData {
    mat4 Projection;
    mat4 View;
    mat4 Ortho;
    
    vec4 eyePosition;
    vec4 data;
};

void main() {
    int instanceID = gl_InstanceID;
    vNormal = av3normal;
    gl_Position = Projection*View*MShip[instanceID] * av4position;
    UVW = av3uvw;
    vViewVec = vec3(5,5,0) - av4position.xyz;
}

The shader always returns instanceID as 0

The same shader on G900H (based on powerRX) works fine.

Thank you in advance for your help
