Houdini learning

Increase Volume Density

// In a volumewrangle

@density *= 10;

Substract any VDB by another VDB

// In a volumewrangle

if (volumesample(1,"surface",@P)<0)@density=0;

//inverse:

if (volumesample(1,"surface",@P)>0)@density=0;

Get bound & centroid

// In a null object

bbox(opinputpath('.',0),D_XSIZE)
bbox(opinputpath('.',0),D_YSIZE)
bbox(opinputpath('.',0),D_ZSIZE)

centroid(opinputpath('.',0),D_X)
centroid(opinputpath('.',0),D_Y)
centroid(opinputpath('.',0),D_Z)

UVs

// In this order : uvautoseam - uvflatten - uvlayout
In uvflatten : Seams = seams
