Hello. I still had these projects sitting on my drive so I was able to create some new screen shots of the configuration in Blender and After effects.
Here’s the Blender Speed to RSMB node and overall compositing chain in Blender, and the setup in RSMB in After Effects, which is basically to point the Motion Vectors parameter of RSMB to another layer that contains the RSMB output generated from Blender.
