Hello,

I'm have a simulation made in houdini and cached to disk as a bgeo sequence, I'm trying to render the particle in arnold but i'm not getting any motion blur.

Thanks
Saber

Does it have the velocity attribute? and did you enable the Geometry Velocity Blur in the

Object and enabled motion blur in the Arnold ROP
