I can render a simple rectangle to an ofFbo. I draw the fbo and see that it worked. I can send the fbo’s texture along to an ofxFXObject (let’s call it fx_blur). I can draw fx_blur to see that it has the proper image/texture rendered to the fbo. When I try to draw fx_blur, I get nothing useful. I’ve tried this with several different effects, in many different configurations. An example project that illustrates the problem is available here.
Any help appreciated.
