I’ve been trying to find somewhere that says just what values are being assigned to what colors of Blenders Vector pass. Does anyone know how the X/Y and movement information are being laid down by blender? Has anyone else successfully used the vector pass in a 3rd party tool of any kind?
the image (RGBA) is based on screen space pixel movement of verticies… R being the x direction from current frame to previous frame, G being y direction from current frame to next frame, B being x direction from current frame to next frame, A being y direction from current fram eto next frame.
I am not sure about 3rd party tools though…
The vector pass from Cinema4D and Blender are very similar. I did create an After Effects project that would extract the information from the C4D vector pass and route that information to a blur effect. This technique would probably work with a Blender vector pass as well.
so, its like the 3d normal maps, only dealing with actual movements rather than normal direction data?
