MtoA OpenVDB sequence file problem

Hi
when importing vdb sequence (The vdb file has density, temperature, heat, fuel, velocity) via Arnold create Volume Node and putting the expression in Frame to load the sequence: (aiVolumeShape.frame=frame) nothing happen, the vdb file sick at frame 1 (smoke_sim.001.vdb), even when moving to the next frame, the expression show the correct frame, but the vdb won't move!
Changing the padding in Volume Node Filename from smoke_sim.001.vdb to smoke_sim.###.vdb seem to work, but another problem appear, all the grid disappear (density, temperature, heat, fuel vel,etc..)
The original file was exported from Houdini (smoke_sim.$F3)
any solutions to this?
Thanks

We've fixed the issue about grids missing when your filename has #### on it. That will be in next bugfix release.

In the future we'll make the workflow simpler, by automatically creating the expression for the animation, like Maya File does when you have animated textures.

Thanks for reporting
