Hey,

I want to make a setup of melting based on depth of object.
It is a flip setup, where “temp” attribute is used as a driver for Viscosity.

Temp attribute is driven by a “acumm” attribute (point propagation), which works by accumulating neighboring points.
I also use volume sample to create a “depth” attribute.
What I want to do is to drive accumulation of point by depth attribute. So what I want is to viscosity to lower over surface faster like an ice cream.

I am very new to this kind of things and I feel overwhelmed.

I have several issues.
1. Isooffset and VDB seems to give different volume sample results. VDB is negative and when I try rescaling (fit), it snaps to one value, loosing its range. The range of values are also strange. It's not from 0-10, or 0-1 or even -1-1 but 2-5 or 4-8. Don't know what to make of it.
2. I don't really know how to visualize numerically (or with color) volume sample in the viewport.
3. I need to transfer depth attribute to attributeVOP where I calculate temp and improvising a lot, I seem to missing a point on how to do that.

I am sorry for being a such a newbie.
I am trying to use logic here but maybe mine fails me.
