Hi,
You can perform an unsharp mask in VEX on a volume like this where the second input is the output of a HeightField Blur, using a Volume Wrangle SOP:

Wow, thank you. What are you inputing into the layer?
height
This is inline with other HF SOPs that expects a layer name.
And make sure to bind height to density:

hi
thank you for your help.
is it okay to write it that way?
float d = volumesample(1,"height",@P);
@height += (@height - d)*ch("amount");
thank!
Yes that's valid as well.
