This node fixes the bounding box problem with nukes native vector blur where it deletes all overscan. This node lets you set a custom overscan which gets carried through the process. In order for this to work you render needs to hae overscan already.
Also I found out that (I have no idea why) it fixes some of those very nasty artefacts that appear when using the motion vector pass from the arnold renderer.

Version 1.1:
Improved bounding box behavior. Now the input bbox of an object can be carried through which results in faster rendering. When there are any problems with the output uncheck "preserve input bbox". This will give you a unified bbox which also works but at the cost of slower rendering.
