arx_anima the karma node or the karma standart rendervars node has motion vectors and velocity aov as default to check. We used them already in production and they work fine, they do not use primvars but a ray level check ray:motionvector ray:velocity
Hey there, I tried checking both the motionvector and velocity in the karma render node, however I still get a blank output. Am I missing something?
Thanks!

Have you managed to make it work? I've been stuck trying to output AOV motion vectors with no sucess
Hi!
Based on my experience working with Solaris, I've created this file which shows different ways to make motion vectors/motion blur work in Solaris.
Thanks so much! Putting in the node finally gives me MB and the vectors. But I can't get rid of Karma actually motion blurring the image. While "Disable image blur" is on, it's also grayed out. So, I only need the vectors. : /
Might have found the solution. IF I create a custom motion vector path "Disable image blur2 is grayed out and I get amotion vector and beauty image with MB applied.
If I just use the one click motion vector path the dialogue "Disable image blur" goes live and you can click it.
Tom Mangold Thanks so much! Putting in the node finally gives me MB and the vectors. But I can't get rid of Karma actually motion blurring the image. While "Disable image blur" is on, it's also grayed out. So, I only need the vectors. : /
Need to check your file tomorrow.
Hey Tom,
Enabling the "Motion Vectors" Pass under the "Utility tab" as shown in the screenshot below should allow you to toggle "Disable image blur".
