是否可以在GLES2.0的VertexShader中使用统一的结构数组？

Question

Is it possible to use struct array uniform in VertexShader on GLES2.0?

attribute highp vec4 vPosition;

struct TestStruct{
    highp vec4 v;
};
uniform TestStruct tmp[32];

void main() {
    // test code
    gl_Position = vPosition + tmp[31].v;
}

I recieved shader compile error.
"uniform variables in vertex shader do not fit in 512 vectors"

My GPU is Qualcomm adreno220.

Do anyone have some information about it?
I am troubled very much.

Thanks.

It is possible. There might be a possibility that your array is too big. Try a number below 10 instead of 32.
