Hi guys I made a Post processing motion blur filter ready to be used on game engines. It works perfectly for me, so please tell me if this doesn't work for you.
if you are using intel card, set 'artifix' to false if you are using nvidia cars, set 'artifix' to true
To use this filter, open your project and File->Append my file, click on Object and select 00MotionBlurController. That's it!
Hope you enjoyed!
