# Instructions
|
|
**For Godot 4.4 users:** I introduced a new Godot 4.4 branch with required fixes, download from it instead.
|
|
|
|
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 MotionBlurCompositor(NEW!!) to it
|
|
3. to that, add a new PreBlurProcessor effect, which is now required, and after it add a new GuertinMotionBlur, SphynxSimpleJumpFloodMotionBlur, or ExperimentalJumpFloodMotionBlur
|
|
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
|
|
|
|
* GuretinMotionBlur - An all around best blur effect, robust, performant, and now also realistic.
|
|
* SphynxSimpleJumpFloodMotionBlur - An effect driven by a novel dilation method using the jump flood algorithm, used in research of realistic blending schemes and focused on being a retrospective blur approach.
|
|
* ExperimentalJumpFloodMotionBlur - An effect driven by a novel dilation method using the jump flood algorithm, uses an added feature to heuristically fake transparency of leading edge of the blur using the past color output.

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.

and heres a paper I wrote on it:
