Re: Soda bubbles within Dspline animation. -Filter Daemon

Hi welcome to this forum. Regarding the filter daemon with Dyverso solvers, I think it is the best choice. The dyverso system is much more accelerated by GPU computing than the hybrido system. The filter daemon can be a little tricky. It could be useful to have a look at the spreadsheet of your emit...

Re: Level of particle details inside the C4D

Hi I don't think that the reduction of particle numbers alone gives you a better result. Instead I would suggest to use the filter daemon inside RFC4D. In this way you can influence the amount of particles in the bubbles emitter by the numerical parameters of the filtering. That worked well for me i...

Re: Animation and particles leaking

This is an interesting challenge and out of curiosity, I tried something similar: a filled paper cup falls on a surface and spills its content. In this project I found that leaking was not such a problem, but over-shooting behavior of the liquid. First, I tried to simulate the dynamics of the cup an...

Re: Animation and particles leaking

I see... maybe better to make the time factor (fps) so that the liquid is not over-reacting to the objects. Alternatively you could use a strong drag-force to calm the liquids behavior.

Re: Animation and particles leaking

Hi

I assume you have not forgotten to turn on "Continous collision detection".All your measures make sense.

But the timing of the alembic still looks quite fast. I would think that further slowing of the motion should make it work.

Re: Dspline to get a ribbon

Thanks Thomas!

How could I forget it..always check the waterline pdfs and the blog for in-depth RealFlow knowledge <thumbs up>

Re: Dspline to get a ribbon

Hi

yes, I see the problem... the beginning of the Dspline almost always acts like a "lens" that attracts the particles and pulls them together.

An alternative approach could be to move the linear emitter along a spline such that the emitter leaves the ribbon behind, without Dspline.

Re: Dspline to get a ribbon

Hi a more ribbon-like shape could be obtained by using a linear emitter at the start of the Dspline and a relatively high "vortex strength". However, it is always a delicate balance between the vortex strength (which produces the cork-screw motion of the ribbon) and the "radial streng...

Re: Import granular to Maya and Vray rendering

Ok, I think I can do it again :P

Granular particle color coded by velocity

Is it something like this that you would like to create?

Re: Import granular to Maya and Vray rendering

Oh, I see, sorry I got that wrong. Well, I have learned a couple of things about V-ray in this course https://www.learnwaterydesign.com where Catalysee does all rendering with V-ray and RealFlow, but I just started. What I do like as render option for granular and other particles data is Krakatoa, s...
