good point! just trying it out with PF, TP. all has the same issue. no velocity vector render directly with particle when motion blur is on. needs to mesher or xmesh out then you get the velocity.

Hallo
i tested the vrayvelocity renderelement for the current release. it seems not to work for now , right ?
i got a weird colored renderelement only if i turn on motionblur.
You can see it in the attached Image. All particles have different colors but the fly in the same direction…

Your screenshots aren't labeled so I don't know which is which.
I also don't understand the problem you're having. You previously stated you were getting no VRayVelocity channel but your last screenshots imply both are returning colors.
Only thing I can think of, regarding your last screenshots, is that it's possible velocities in the VRayVelocity channel are not being calculated at the correct time scale. The VRay SDK is a bit confusing in that regard and once I confirm the problem you're having I can talk to the devs about it.

i only get a vrayvelocity if i turn on motionblur.
to the screenshots: first is pflow, second is tyflow.
i am not sure how i can help to define the issue more

am i the only one here who have this Velocity Problem?
i tested with the newest Version of tyflow and tried a scanline test. same Problem. there is nothing in the Velocity nor in the vrayvelocity channel.
if i turn on the motionblur there is Information but its wrong. and on the other Hand: if i render an Image with motionblur i dont Need a Velocity chanel anymore.
