Vdb displacement problem

I'am trying to displace a Vdb using noise with no luck at all. The vdb was rescaled and resampled (VDBResample) and still, no displacement on it. Nothing moves at all. Not able to reach the vdb bound clipping at all, witch is easy to get however on the original not scaled vdb.

Thanks!

Sorry, found the problem.....needed to boost the color2 output to see something of km scaled vdb's. Not sure why amplitude in the noise stop increasing toward the bound padding.

Thank you so much!!

Here's an example file for displacing a vdb volume with the standard_volume shader: volume-displacement.zip

Can you provide more information/screengrabs/upload simple scene?

Does it work with a different VDB?
