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

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