[SOLVED] PGraphics or PImage as Uniform not working when using GLSL in Java OpenGL

@hamoid

I tried running the program but it gives me a NPE at sh.bind() .

@kesson I get that too. Seems to be caused by setting a texture uniform prior to first bind. At least, doing this gets it working for me.

// Load the vertex and fragment shader
  sh = loadShader("frag.glsl", "vert.glsl");
  sh.bind(); sh.unbind();
