Hybrido 2 also supports OpenCL GPU acceleration to speed up simulations. A new meshing algorithm has also been introduced, so now one can get the detail of the base simulation into the final mesh. The base simulation alone gives the user quality and detail that wasn’t possible with the old system, even adding tonnes of additional layers of particles on top. The simulation took its time, but the amount of detail was very high this wouldn’t have been possible with the old Hybrido system. Scene nodes are the new node-based way to work in RealFlow 2013 Hybrido 2 integrates extremely well with Caronte RBD. While testing, I was able to simulate a waterfall consisting of more than 200 million particles (base simulation, without additional layers) on an i7-3930K Intel-based workstation with 16GB RAM.
However, Next Limit has addressed the issue by introducing a FLIP solver to Hybrido 2 and renovating the secondary systems for the creation of more detail, foam or other additional elements for simulations. This worked fine in many situations, but Hybrido was limited: it was hard to get an acceptable amount of detail out of the base simulations, and one often needed lots of additional layers of SPH on top in order to get the desired quality. Hybrido offered a simplified method for simulating the base liquid, so SPH was only needed for certain high-detailed areas. SPH enables you to simulate virtually anything that takes a whole lot of detail, but those highly detailed simulations take their time. Until then, this had been hard to do with RealFlow, as its standard SPH-based particle solver is more targeted towards splashes or tabletop-scale phenomena. Hybrido was first introduced in 2010 with RealFlow 5, as a system for simulating medium and large bodies of water. In comparison with the previous Hybrido system in RealFlow, the new FLIP solver feels like a quantum leap – faster, more reliable and allowing much more detailed simulations. Now, a FLIP solver (FLuid Implicit Particle, a method originally invented in 1986) is the base for the liquid calculations – basically the same technology that is used in other packages such as Naiad or Houdini. In RealFlow 2013, the Hybrido 2 system for simulating large bodies of water like rivers or oceans has been completely revamped. The tutorial continues to see the simulation rendered in Maya using Krakatoa MY and V-Ray, and then finally following the workflow through to the end sees the compositing all the elements rendered with Nuke.The ability to preview simulations using Maxwell offers new workflows to the artists
The “hybrid” part of Hybrido is from the fact that it uses both the detail preserving particles as well as the grid based simulation solutions to offer the best of both worlds. The technology was integrated in RealFlow to assist in creating larger liquid simulations realistically and practically. Hybrido is actually an acronym pulled from what it does – HYBrid laRge dImension LiquiD solver.

And we’ll color the Krakatoa render by velocity using Magma Dieuwer Feldbrugge - Īs far as what Dieuwer takes you through, it is really the standard and basic water being actively poured into a container -Something that you probably have seen many, many times before, probably due to the fact that it is a great place to start.Ībout creating a simulation and following it through from rendering to final compositingĭieuwer shows how to simulate the liquid forms in RealFlow 2013 with Hybrido – RealFlow’s latest fluid technology. In the next two parts we will render this sim and its mesh in Maya using V-Ray and Krakatoa MY. In this part I will show you how to simulate the stuff that we need using Realflow 2013 and Hybrido. His look at Integrating Realflow mesh and particles using Maya, V-Ray, Krakatoa MY and Nuke is really all about creating a simulation and following it through from rendering to final compositing. Offering some insights for new users or for people who want to get started with using higher end tools to create and render simulations, Dieuwer Feldbrugge has you covered with his first tutorial.
