3DArtist, oggi vediamo una delle grandi sfide per gli artisti 3D e CG, quello di ricreare gli intricati vortici dello shader sulla superficie di una bolla di sapone nel rendering?

Come rendere belle bolle di sapone in 3d?

In questo video tutorial, Moritz Schwind di Entagma farà luce su ciò che serve per impostare un veloce simulatore FLIP creando uno shader di vortici altamente dettagliati in Houdini.
