Instructions

1. take the contents of the "addons" folder and move them to an addons folder in your project.
2. add an environment node, add a compositor effect to it
3. to that, add a new PreBlurProcessor effect, which is now required, and after it add a new MotionBlurSphynxJumpFlood

instructions for radial blur meshes can be seen here: https://youtu.be/eslsw9do4Kc

WARNING: if you want transparent objects to render on top of the blurred background, you can move the pre-blur-processing and blur post process effects both to callback type of pre-transparent, At which point it would not work if you have MSAA enabled, so make sure to also turn that off.
