Motion vector from animated sequence

Recommended Posts

Hello !

I try to create motion vector from 2D animation sequence for using in game engine (unreal). I try first to render the result of volume optical flow using volume slice and gamebaker but there no files when I press render and no error message neither.

What I'm doing wrong ?

 

Thanks a lots :)

Ok I made it ! 

The big mistake was I didnt converted the volume slice mesh into polygons.

I used the "sop simple baker" from game dev tools. 

I normalised the vector using the attribute promote to get the min and max and put it in a pointvop.

Things to fix : right now I just add arbitrary number to my normalised output to get a perfect ".5" value on "blank" space. Didnt figured a way to do it procedurally.
