Molecular addon: snow ball test
A test by PyroEvil of his Molecular add-on.
PyroEvil writes:A little test to achieve this kind of effect with my addon:
Not really near of that but not too bad for a first try with a small amount of time to tweak it. The snow is probably too sticky and for sure , missing a lot of particles to achieve the same resolution.
Stats:
- Numbers of particles: 400 000
- Numbers of frames: 180
- substep: 32
- Simulation time: 96 sec / frame (6.0 hours )
- RenderTime : 4min / frame (14 hours)

wow you should work on that script it looks already pretty good but still needs much improvement
Very perspective addon. Glad you’re developing it.
With the ground snow, you could use the Dynamic paint.
This would reduce the amount of particles used and perhaps make simulation times faster.
I feel it would also give you more particles to play with in the case of the snowball and snowman.
Hope that helps?
Wonderful work, keep it up!
Good point , not sure about the dynamic paint things but you give me some idea to optimise these simulation. Now a test with 1.7millions of particles is calculate with the same resulotion I got with 3.2 million
Will it be significantly faster calculating under C?
thanks a lot. Yes , I never code this project to be physically accurate. I’m not a dev, just a artist that learn coding for fun in the last two-three years. I don’t change my code to do this, just use and tweak the parameter. So from the beginning , anybody can do this kind of “effect” with my addon. it’s coming from a challenge then somes friend give to me last week after see the disney video.
I guess that many cool 3d apps were started by artists :) So who knows, maybe some time later your Molecular will be developed to something cooler and more complex. We’ll see what Lukas Toenne will do with nodes.
If Blender go with nodal particles like the branch of Lukas does and have enough math nodes and the system is enough flexible , it’s for sure I do a node version of molecular. If you see on my channel , I already test a bit the version of Lucas nodes particles systems.
Oh and I forgot , code it with cython (python C extension ) give a code 100-200 times faster with multithreaded.
Already or it will be done in future? (yes, I’ve heard about cython).
Already coded with cython and multithreaded too.
Great job. This will certainly give the user more tools to work with….
Those two ref video from disney show a very wet snow, it doesn’t attach to it self in layers like this normally
First of all great work PyroEvil!!
The Molecular script is amazing!
Second.. what about a tutorial? I find your addon a little hard to understand..
I think we’d all rather him spend his time developing the code further than making a tutorial for us noobs :)
Good point. Also, a good developer isn’t necessarily a good tutorial writer. You need people who are curious to find out how things work, can come up with an appealing application and then write a short and to the point guide. I loved doing that stuff when Blender was just released, but it takes a ton of time :)
Yep.. your are both right!
This stuff can become a Revolution in the CG world. For now, all objects that we make are empty, and this is a great difference between the physic world and the 3d world. With this technics, this characteristics change, 3d world also shall be molecules like the physical world.
Hi, thanks a lot to everybody for great comments.
3 video tutorials are now available from yesterday. I agree with Bart , I’m not good to make tutorials :) but hope you like it. I probably present to BlenderNation a article for this tutorials when I’m ready (in few days … I suppose to present this video in this article too but somebody is faster then me. ) to officially announce the release of my addon ( I don’t think to continue to work on it for now and start a new project ). Just to mention I not touch to the code for about 2-3month and this effect is done by ajusting the right settings. So this effects is possible to make from the beginning of my addon developpement. Just to mention I never intended to be accurate like Disney ;o) I dev my own “physics” that probably not “physically” accurate but more versatil to make different kind of effects. I’m a artist more than a dev, I learning to code in the last two years. A fun experience. A version of this video with more resolution is coming.

Brilliant, thanks! Okay, I’ll wait until I hear from you before I properly publish these then :)
hahaha no problem with this ;) I just realize it when I see my video go up to 5k views in 1day and a friend tell me I have a article about my video on CGChannel. :)
Congratulations :)
You are most dangerouse for Autodesk and Disney
fascinating watch, thanks for posting
