Hi Everyone!
I am tearing a cloth in Vellum and rendering with Redshift.
The Velocity attribute is there, the Deformation Blur is ON in the ROP.
However there's no Motion Blur in the render. I tested in progressive and bucket mode.
I also tried promoting the v attribute to vertices and primitives. Nothing seems to have an effect.
Regular animation is being blurred e.g. Transform SOP.
Is there something I'm missing?
Thank you in advance!

Have you added redshift properties to the vellum geo container and enabled the use of the v attribute for MB in there?
If not try that.

Cheers
