Re: Hybrido export do i need RPC and VDB? both?

If you want to simulate splashes or foam particles from the Hybrido core fluid then the OpenVDBs are required, because they contain the fluid's distance and velocity fields from which these secondaries will be created. The individual emitter resources are only needed if you want to render their part...

Re: Graph Water To Foam ?

Hi Dmitry, Yes, it's possible to add randomness, but currently I can't see how this addition should help to get more particles around an existing one. OK, I have a rough idea, but most probably this approach is not what you're looking for. The randomness I was talking about was meant to create range...

Re: Dspline to get a ribbon

I've seen this discussion already, but don't have an out of the box solution. Viscosity won't help too much here. What you need is surface tension, but I doubt that you'll be able to get this shape just with high surface tension. Of course you can give it a go and I'd start with (perhaps) animated v...

Re: Dspline to get a ribbon

Had to take look at the script myself again. It's been a while... steps The script evaluates the template spline's position values in space - it subdivides the spline into tiny segments to get resonable position values. That's why you need high numbers here. maxDistance This is the maximum distance ...

Re: Dspline to get a ribbon

Which attribute you're finally using is totally up to you and hard to tell from my perspective, but if you're happy with no. of neighbours why not ;) Should I use a different Mesh for each system? That's also up to you. If you have to keep the fluid visually seaprated, e.g. through colours, use 2 me...

Re: Lack of "Frame Offset" for the Cache

Are you using the GPU for your simulations? Maybe you want to give this scene a try without the GPU to see if it's still crashing. Another reason could be that the number of particles is getting too high at some point of your simulation, or that there are some super fast particles. In the latter cas...

Re: Dspline to get a ribbon

Great to hear that you're getting there. With regards the isolated droplets and tendrils you can use a filter daemon and shift certain particles to a second domain. This domain can then be influenced by a separate, much weaker drag force, and/or a surface tension daemon, for example.

Re: Dspline to get a ribbon

You can also try that freebie: http://waterline.tv/downloads_03.html. Just look for the "Fluid Ribbons" chapter ;) This project requires a script that's listed in the magazine as well. This script is responsible for the emitter's orientation along a spline/animation curve. If you don't wan...

Re: Lack of "Frame Offset" for the Cache

The bug with Dyverso and the retimer has been fixed in the latest version, so it shouldn't crash anymore. Are you on 10.1.2.0162? And, yes, meshes shouldn't be retimed, because you have a changing topology there: RF isn't able to interpolate the changing number of vertices and polygons. Therefore it...
