Molecular Script Addon
The Molecular Script is an addon for Blender 2.8 that makes particles collide. In addition it makes links between the particles. So making collisions and links are the two most important things the addon can do.
Since there are a loads, read: loooaads, of settings in the addon, I will show you to get the hang of the addon. Start with a simple particle system in the learning fase. This because you need to re-calculate every time you change a setting. The video below gives you a good introduction to this addon.
How the Molucular Script Addon works
For those who don’t have acces to the video, here are few notes of what is discussed in the video.
- Start with a simple particle system. This saves a lot of time. Later, when you get the hang of the addon, make a more complicated particle system.
- For example: 50 particles, starting from frame 1 to 50. Give the particles a life-time of 130 frames.
- Then in the Properties Panel – Particles, enable: Molecular Script.
- In Short; Enable collisions and links. Collisions prevents particles to intersect but can give a kind of explosion effect. To get rid of that explosion effect enable Links, so that particle don’t fly away to far. (Sorry for the layman terms, but it’s probably more clear than using academic terms. If not, let me know).
- Because you need to run the simulation after you change any setting, it’s an idea to right click on the button called “Start Molecular Simulation”. Then choose for the option to add it to the favorites. If you press then Q, you will see the option to Start the Molecular Simulation. And so, you don’t have to scroll down all the time, trying to find that button. For more documentation look on Pyroevel’s page, see link below.
Where to download the Molecular Script Addon?
The latest version for Blender 2.93 seems to be available here: https://github.com/scorpion81/Blender-Molecular-Script/releases This addon was written before by Pyroevil, but ported over to Blender 2.8 by scorpion81. There is another version here: https://blenderartists.org/t/molecular-for-blender-2-8-2-9/1285205 which worked for me in Blender 2.93 but it seems not for everyone?.
In case there are any problems with the installation, read the notes on Pyroevil’s page which is an old page but may help.

Can i run the “Molecular Simulation” within a script in Blender? Without having to click the button?
Got: ImportError: libpython3.7m.so.1.0: cannot open shared object file: No such file or directory
When trying to activate
Using Blender 2.91 on ubuntu 20.04
sudo apt-get install libpython3.7
I am Getting This Error Only……

Did you ever get this solved? I have the same error on PC and Mac so I’ve never been able to use Molecular
Did you try the new version on: https://blenderartists.org/t/molecular-for-blender-2-8-2-9/1285205 ?
I have the same error, did anyone find a solution?
There is a new version on : https://blenderartists.org/t/molecular-for-blender-2-8-2-9/1285205
Did you try that one?
Appreciate the reply, but I’m afraid I get the same error trying the version in your link, and Pyroevil’s page (to debug install issues) seems to be gone.
The latest version posted to github cleared up the error I was receiving previously. The strike-out link at the top of this page will take you to it, or you can find it here:
Hi, thanks for the update. I will adjust the article.
