I am trying to figure out why there is no data being rendered to the Velocity Pass. It just looks empty, with the 0.5R, 0.5G colour.
I have a moving camera and a moving alembic cache, the rest is static geo.
Do you know why nothing is being rendered to the velocity cache?
When I output an image sequence with the MovieRenderQueue, this layer in the EXR is therefore empty.
Thank you in advance for your help,
