JFA_driven_motion_blur_addon/README.md

# Instructions
1. take the contenst 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 SphynxSimpleJumpFloodMotionBlur, GuertinMotionBlur, or McguireMotionBlur
4. for debugging, add a "C","Z", and "freeze" input events, and then a DebugCompositorEffect to the compositor effects. Then, all you have to do is toggle "Debug" to true on whichever effect you want to show debug for

instructions for radial blur meshes can be seen here:

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.
