Hey all!
I present to you my Motion Smear - Multiples nodegroup! The free version!
This one is for creating those motion smear effects you usually see in comics, where to suggest motion, multiples of the object/limb is drawn to create that motion blur-like effect. This one does a following and preceding drawing using the vector blur node.
Most important thing - HAVE FUN! :D
I included an extra nodegroup to help you isolate specific objects for the multiples. The other groups were created just to clean up the wires a bit - feel free to explore them to learn more about outlines and how you can manipulate the nodegroup for various results!
As odd as it is, I have not thought about that, as in at all, LOL. At this point, not without some serious modifications on the inside. What it does to fix the brightness that gets dimmed with alpha, is add it over itself. You can turn that off for the alpha channel and force transparency. If you got some solid experience with the compositor, you'll be able to find it very quickly - everything is labeled in function sections with frames.
Unfortunately, not as far as I know. You need the vector pass in order for it to work. According to the rewrite progress - the Vector pass should be on it's way speedily! :D You can also combine engines, letting Cycles give you the vector pass and using Eevee for the visuals.

VERY cool! Is there a way to make the smears translucent as well? Either way, thanks so much!
