Motion Vectors, RSMB, After FX integration Tweet

[Joanlaninja]

Hello, I am desperate. I have a rendered plan of a helicopter with its motion blur extracted as a motion vector pass. The areas without MBlur are gray and everything should be in order. But there's no way to composite it in RSMB and make it work in AfterFX. Everything I see on the forum (I've been searching for useful information for quite some time) is clearly outdated or provides confusing or useless information.

Is there any way, any place where I can find something useful to properly do the post-processing of the shot? I have masks, cryptomattes... I've tried separating the blades, separating the helicopter, separating the background... Nothing works and there's no way...

Thank you very much
