VectorBlur
VectorBlur: motion blur along a vector layer (motion from AIVectorGenerator, ScanlineRender, Cycles or EEVEE).
VectorBlur: motion blur along a vector layer (motion from AIVectorGenerator, ScanlineRender, Cycles or EEVEE). Motion amount scales the vectors; shutter in frames with a shutter offset (centred, start, end, custom); samples; vectors can be forward + backward or forward only; v up matches Nuke's vector convention.

Nuke equivalent
No Nuke class. In a .nk file this node is written as an Oink node that Nuke will not recognise.
