VRayVelocity channel

[hkroeber]

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
