I was working on pretty simple simulation and found very strange thing happening. After I built mesh I noticed this Dyverso_01.jpg Of course if I smooth the mesh it looks better, but it has no details at all. I checked particles and noticed this Dyverso_02.jpg I tried Dyverso SPH particles. Looks th...

Yes, that is how I do it ;) Thank you for mentioning C++ source code. It was really helpful. Now I see that there is a function setInternalForce(), which is somehow not presented in a list of Python's functions in the Help documentation. Now I have another question :))) Well, I'm a C++ guy (mostly I...

Hi, I keep playing with scripting :)) I tried scripted liquid (Standard Particles/type: script) and found something confusing. There is a "def computeInternalForces( emitter ):" section in a Script editor. So, I compute internal forces there, but how I suppose to utilize them? I mean there is only s...

I have similar problem with Dilate filter. It's very slow. Sometimes it takes 30 minutes or even more.

Well, you can simply create an initial state from frame 1 or 2 or whatever. Then you'll have particles at frame 0.

Oh, it make sense

Thank you

Oh I feel a bit shame now :))) I misunderstood the particle radius term :)))) Thanks for clarification ;) By the way I was looking of some way to get initial distance between particles before the simulation is lunched :) Zero frame usually has no particles (unless Emitter's volume parameter is set t...

Just an idea, but what's your scene scale?

Scale is default, 1.0

Hello! According to the Help of Realflow distance between particles can be found like this: radius = 1.0 / (1000.0 · Resolution^1/3) (in meters) So, for resolution 1.0 distance is 0.001. For the resolution 2.0 distance is 0.000794. Emitter is a square, 1m*1m. When I calculate the distance with a scr...

Thanks again for the additional information. Unfortunately, I can't say very much here since I'm not on 3DS, but I'll pass it to our developers. Did you think about a scripted import solution? Could this be an option for you? I din't think about it. For now, I can use alembic files without any prob...

Just some observation: When createVoxelization() is used with standard particles it cause no crashes, but (I have this kind of BUT too often in last few weeks :))) ) it slows down searching process dramatically O.o Without createVoxelization(), searching Standard particles works much faster then sea...
