So I finally figured out how to use this for my own game but I'm running into some issues. My goal is to blur out the background image and then have game images for my platformer un-blurred and then blur the ground in front. Sort of like a tilt-shift camera effect. I have my background on my background layer, and then a mid background image on an asset layer but the minute I turn off interpolate pixels in gamemakers options (globally) I run into all sorts of shading issues with my images when I compile. Just wondering if you could potentially shed some light on how I might correct this. Cheers.
