Velocity or Motion Vector Pass

Eugen Fetsch · October 18, 2019, 03:12:17 AM

This is a special request, but this pass is so crucial to create nice and cheap motion blur in post.
If I render an animation with motion blur, it becomes almost impossible to separate objects from the background using the clown pass for color adjustments or other post production effects. A velocity pass would add the possibility to create a believable motion blur in compositing applications and save tons of render time.

Would love this as well!

It would be an outstanding feature!

Curious, is this a thing in other engines?

Yep, but since KS isn't as popular among motion artists I can see why it has not been a priority yet. With the bettering of the animation side of KS this may come into play more and more. Most other 3rd party render engines have some sort of vector motion pass that can be read into AfterEffects, Frischluft, nuke, Houdini, etc...

What are you doing to my wallet? Never noticed Frischluft before. Nice DOF in post!

It's just a pity that OFX licenses are always more expensive than other versions.

P.S: We still have RSMB to work around the motion pass.

Yeah, its pretty nice. Been around a long time and they really have a nice smooth look to it. Plus the name, you can't go wrong sounding smart when you talk about "Frischluft."
