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
