VDB volume data from attribute

Recommended Posts

Hi !

i'm trying to get volume data from points attribute

pls see the attached picture 

in this case i set an attribute to some value and want it to be sambled into new VDB volume.

it works like surface "wrapped" around my points (red area). and it's empty inside, although there are points inside with the attribute set to positive non-zero value

btw it works fine when i set vdbfromparticles SOP to Fog VDB - it fills all volume where points exist

 

Is it possible to sample any arbitary attribute into VDB like Fog VDB option does?

jsut leave that half-band voxels and radius scale at default and you should be good to go

Unfortunately NO!

the default parameters produce the same effect

as you can see the inner area is empty  although i have points there

You create a surface vdb which creates necessary data on the surface only by definition. But to simplify the process you could use a fluidSource sop which seems to fill the interior.

balance the values and it should work just fine
