Velocity pass + after effect + RSMB

[PEgaz]

HI,

I've got problem with implementing Corona Velocity Channel in After Effect using RealSmart Motion Blur - any one used that configuration with success, if so please help.

There's one topic I found: https://forum.corona-renderer.com/index.php?topic=11510.0
but even going with DeadClown advice I can't achieve result comparable with Vray Velocity Channel output that I used a lot earlier with RSMB and everything worked well and acceptable.

thanks in advance and regards

Really no one used Corona "version" of VelocityChannel with success using Real Smart Motion Blur plugin in After Effect?

Sorry for ressurecting the question :) .... I didn't want it to vanish  and really hoped someone can help, because I'm in deeeeeep trouble.
I thought it would be as straightforward as ... it seems to be (was in Vray)  - but I'm eating my tail trying to figure out how to make it work with no success :(

regards

Welcome to the boat of complaning about the vector pass :D
Last time I properly checked was here including video.
I found, that you had to follow DeadClown's Normalization process, which you already found, but still the Output was Worldspace (thus the teapot comparison was wrong), not camera space, which defeats the purpose of a vector pass for MotionBlur.

The discussion ended with the lead dev stating, that a camera mode is now included, I didn't verify this on my own however, as I didn't need it for my projects.

Have you tried DeadClown's method with the Camera Mode?
I will check this evening again, whether I can make it work.
If not, then we can both perma spam the devs with mean smileys.

Camera Mode did indeed come out and adjustments were made in 1.5 (https://corona-renderer.com/blog/corona-renderer-1-5-released/) - prior to that, things may not have worked properly. A video tutorial was made after that, for Blackmagic Fusion (as it is free, and not everyone will own a commercial plugin like RSMB) - that tutorial is here in case it is relevant to RSMB too:

Let us know if you are still experiencing problems!

Ohh awesome! I completely forgot the tutorial existed. Recall it seeing in my sub box a long time go.

Thank you guys for your tips.
RSMB for AfterEffect have no possibility to choose vectors/channels corelation - I tried with the DeadClown's Normalization process but I couldn't find way to make it look as Vray test I did. (But I'm not an AE guru :)  Evidently some areas that should be blurred were not and the effect I achieved was a little odd.

If nothing works I'm gona meet Fusion closely.
Pity something that worked strightforward for soooo long now needs such an extra tweaking philosophy, but ... maybe the RSMB workflow if not so obvious/commmon as I thought it is.

It kinda is, it just uses the old way of utilizing Image Vectors, with no depth in mind. A shame revisionfx didn't bother updating RSMB, the most widely used plugin for 3D post Motion Blur, for newer formats.
