Exactly what I needed, works so well with my animated main menu. Thank you! (:


I'm so glad you like it! :D It's looking great!

Thanks a lot for the comment ^^

Hey, real quick question... you haven't really showed it in action and the demo doesn't have the option either so i'm curious, how feasible is it to use this to blur SPECIFIC sprites on rendering? (potentially sprites that tile/loop horizontally by being drawn in a loop)

I use a camera object to manually draw backgrounds parallaxed on the fly (so it doesn't break splitscreen parallaxing by directly changing the layer coordinates), and i was thinking of applying various levels of blur to each parallax layer based on its depth, but it'd have to all be in that one single draw loop so blurring an entire area isn't really feasible since it'd bleed into layers behind the front ones.

Hi! Does this work with Game Maker Studio (v1.4.9999)?

Hello! The asset is only compatible with newer versions of GameMaker, sorry.

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.

Hello! Could you show me how it looks visually? Is pixel interpolation disabled from blur (when you disable in your game)?

Hey! I like the extension, thanks!

Please help fix the drawing on GUI

video link :


You removed the background from the room, and the game was left without a image to clear the application_surface buffer. Then you drew a sprite in the GUI, but the GUI is not affected by the application_surface, so it was not able to get the game image correctly. Draw the background sprite in the Draw Event (this way it will be on the application_surface).

Thanks :D


Hey there!  How should I credit you?  Just tossed the blur plugin into the game and it went it so smooth. :D

I'm glad you liked it! Credit is not necessary, but if you want, I'll be grateful :)

It could be my nickname.


This blur has over the double the perfomance compared to the GMS newly implemented "Filters and Effects" blur filter, it's also MUCH more versatile, can be applied to single object or an area or fullscreen. Super easy to implement and control!

Thank you for saving me so much trouble! What a great release!


Thank you enormously for the words, I'm very happy that you liked it! :D


This asset is awesome.

Thank you! Very cool how you used it, I liked the ogre!
