Re: Realflow rendering

Well, not wanting Christian to be all alone on a cold winter's night ........ Thank you Forester :P Ideally, a forum is a place where several people come together, but this one is a little too specialized and the numbers of RF users appear to be declining. Anyway, rendering bubbles and foam is a fo...

Re: Realflow rendering

Well, rendering the foam depends on the options that are available in a specific render engine. Personally, I am using Redshift most of the time now, have not used Octane. Redshift offers a couple of options when you use their render tag on a particles source (custom object, point instances, spheres...

Re: Realflow rendering

Hi
so I then use the scatter object to add geo to the imported particle meshes. (spheres on each point)
Just to be sure we are talking about the same... you use this to render foam, right? Like on the crests of the waves?

Re: Looking for Help

Hi in the video, everything seems to be well organized and working so far without a mesher. So, the problem was not visible in the video, or did I miss that? When the option "use cache" is enabled, it will try to load existing particles and mesh-abc's and maybe there are non available, so in order t...

Re: Dyverso not using GPU !?

The GPU load with a GPU-render engine, Redshift3D, was up to 70% during active rendering with the same machine. In that situation with 9GB memory load, a different situation.

Re: Dyverso not using GPU !?

This is a question for hardware experts, and I am not one of those ;) Nevertheless, it may depend very much on the type of simulation running, if the system has to switch all the time between CPU and GPU, for example. In this case, simulation with a larger amount of particles would benefit more. Als...

Re: Melting object

Ok, I made a quick re-simulation and render of that "tendril dropping" scene: https://youtu.be/8GKH05OhDLo The tendrils form nicely with the sheeter filling in Dyverso PBD particles, but it is at this stage not really a viscous simulation. What is especially missing is the thinning and stretching of...

Re: Melting object

There are many possible variation of parameters, sure, but what is the goal in the end? And that determines the solver to be used (sph, viscous, semi-viscous, elastic). If it should be a natural substance then looking at video footage of such a phenomenon could help (lava, liquid iron etc.).

Re: Melting object

For the "stringy" appearance I have introduced the sheeter daemon that acts only on the molten fraction, the second domain. But I have reduced the age setting of the daemon because wanted to avoid that the mass of the molten material increases too much when it is already on the floor.
