Tips and Tricks: Creating secondaries from Dyverso sims. English and Spanish

Hi everyone!

Someone asked me for creating secondaries particles as splashes, bubbles, etc, from Dyverso simulations. It is not possible to do it directly as Dyverso doesn’t allow secondaries yet, but we can follow this tutorial to create the secondaries.

Alguien me pregunto como se podia crear particulas secundarias como bubbles, splashes, etc desde simulaciones de Dyverso. No es posible hacerlo directamente pero puedes seguir este tutorial para crear esos secundarios.

  1. Been waiting for something like this for ages. But really very confused. When I add the first node in the graph and try to add the Dyverso domain, it doesn’t appear in the list, only the HY_Domain does, so I can’t add it😦 Any ideas?

    1. Yeah. A new patch will be released in few days fixing that. Meanwhile, you can use another hybrido domain to load the particles rpc fron dyverso and then following this tutorial for creating also the vdb necessaries for generaring the secondaries.

  2. Luis Miguel, thank you very very much for this tutorial.

    Now I am wondering why not to simply replace my hybrido simulations by dyverso domains, and get the splashes and foam as you show in the tutorial.
    In a previous tutorial you said that it is a matter of scene scale. You said that dyverso is suitable for use in small or middle size simulation. But what is a simulation too big for dyverso? It is so, it depends on size, or is a matter of maximum quantity of particles from which is better to use hybrido?
    Bearing in mind that dyverso is faster, which are the advantages that hybrido still having to use it with regard to dyverso? And what about standard particles?Do you think that is a matter of time that in future versions of RealFlow dyverso will replace both solvers due to it is faster?

    Again, thank you very much for sharing your knowledge.

    1. Hey, a big simulation for dyverso is more than 20 millions for example. Hybrido, depending on the machine, is able to simulate until 500 millions of particles in one single machine. Dyverso won’t be able to reach so many millions of particles as it would need a lot of resources which are not possible nowdays.

      For medium and small scale, dyverso is great but imagine the pacific rim movie with only 20 or maybe 40 millions of particles. For some shots, there were at least 300 millions of particles. 😉

  3. Hey Luis, thanks for this tut, very useful. Just a quick question: what scale settings do you use in this tutorial?

    1. Hey, thank you so much for watching the tutos?. I always use scale 1. If I want to scale something I use a null and all geometry or emitters are parent to it 😉

  4. hey I found out some strange issue with this method. Wnen I locked timeline and simulating the hybrido get me more particles then dyverso and it is not line up with dyverso, obviously I got no idea why is that????
    Apart from that this tut is just awesome!!!!!!!

    1. Hey, that is because the particles are not being removed as the script is affecting per frame. If lock button is activated the simulation won’t know about frames. 😉

  5. Excelente tutorial, muchas gracias. Yo utilicé partículas standard y las copié a un dominio de hybrido, aunque no tengo resultado estable, no es la misma simulación. ¿Qué shaders utilizaste para el render de las particulas?

    1. Hola Joshua,

      Hay un material dentro de RealFlow para las particulas que se llama air. Ese es el que utilice para las particulas de las burbujas.

      There is an air material inside RealFlow in the Maxwell tab. I used that material for bubbles particles
