Right now I am trying to pass an array of ints into the fragment shader, and am doing this through a uniform array:
uniform int myArray[300];
And filling it outside the shader with glUniform1iv.
Unfortunately, uniform arrays larger than ~400 fail. I understand that I can use a "uniform buffer" instead, but can't seem to a find a full example of passing a large 1D array into a fragment shader with buffers or otherwise.
Could anyone supply such an example?
