pyroevil/blender-molecular-script

This is my molecular python script for blender. A bit similar to Lagoa Multiphysic in Softimage.

blender-molecular-script's Issues

Parenting objects to individual particles

Just a simple idea how Molecular script could be used in destruction of solid objects (like concrete)

Replace KD-Tree with Octree

Hi bro, i heard that you wanted to replace KD-Tree with Octree.
Long story short, i managed to write the Octree version last night to test it:

the results are more or less the same, it can crash on breaking point (sometimes works fine no issue) that i need to investigate what is wrong with it but i in the matter of performance I did not gain so much speed from it.

I think the actual bottleneck is Blender and the connection between Python itself. every time we have this connection all processes should respect the GIL lock and we depend on particles and collision in the blender so I imagine with every update how much performance we could lose.
One thing that I noticed with Octree we need almost 3 times more memory. i hope that helps.
i think i do not know how to use the debugging symbols in Blender it gives me nothing, absolutely nothing. can you help me with that?

Pyro Evil Website is down

Hi there, I'm trying to download the latest version of this add-on from the link you've posted but I'm getting an "Account Suspended" message from your website.
Is there anywhere else I can get this addon?
Thanks,
Ben

Some memory issue

Hi, I'm using Pavel's fork on blender 2.8
Ever since older versions until now, when I start molecular simulation my memory usage skyrocket. For simple 3000 particles, 0 substeps, when I reach about 80 frames calculated blender is using 5gb of Ram and doesn't release on cancellation.

Break the code into modules

But first you need to get rid of global variables.
Here are the approximate names of the modules:
__init__, operators, panels, properties.

Activate Particles Linking with Others Option

Create a check mark that will activate links to other particle systems.
Now connections are always created.
You need to be able to disable them.

Groups as an integer value

Change the group type to an integer value.
Now there is a limit of 11 groups.
It is necessary that this restriction does not exist.

Not able to clear interrupted baking simulation

Firstly, thanks for making this great plug-in 😍

When doing the simulation if fx. force shutting down Blender, or crash and reopening the file the simulation baking button is stuck in the countdown mode, and I am not able to clear it. Even if making a new object, it is still stuck. I would need to make a new blender file and start from scratch.

Running from commandline not working

When I try to render a file from the commandline, it seems that molecular is not running. Everything just renders as if normal particle physics runs.

I've tried setting the -y flag and adding it to the --addons explicitly.

Am I overlooking something? Is there a way to trigger the addon via python? (pretty new to programming blender with python)

Bake UVs Bug

if you enable the "Bake UV at ending" option, there will be an error:

SPH Fluid Simulation

Is it possible to make so that the particles behave in this way?:

Linking Group

Add the ability to specify a group to create links.

this plugin still woking on Blender 2.9?
