Molecular addon: snow ball test


A test by PyroEvil of his Molecular add-on.

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.


  • Numbers of particles: 400 000
  • Numbers of frames: 180
  • substep: 32
  • Simulation time: 96 sec / frame (6.0 hours )
  • RenderTime : 4min / frame (14 hours)

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. 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

    • 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.

    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.

  3. 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.
