How do you break apart voxels?

[Rob Ot]

Hi! I was wondering if anybody knew how to turn an object into voxels, and then break it apart? I’ve tried the Remesh modifier, but it just changes the surface, and doesn’t actually create voxels…

If my description isn’t clear enough, I’m looking for something like Teardown(https://store.steampowered.com/app/1167630/Teardown/).

Thanks!

Hi Rob @modelmonkey ,

How about using Geometry Nodes, maybe something like this:

If you Apply the GN Modifier, you can go into Edit Mode and see that you have all those individual cubes. (P > Separate by Loose Parts, back into Object Mode, Object > Rigid Body > Add Active, etcetera.)

I didn’t go to your link, by the way, your description was pretty clear (I think).

Hopefully apart from Martin’s solution, this tutorial could help? It’s a long shot, I’m just guessing because of the title.

Hi @spikeyxxx, thanks for your reply. I’m fairly new to Blender, and I can’t find mesh-to-volume, only volume to mesh. When I create a volume, I can add the mesh-to-volume modifier, but not in the node editor. Thanks.

Hi Rob @modelmonkey ,

The easiest way is to use the Search, when you use SHIFT+A to Add a Node, there is a Search on the top and if you start Typing:

Mesh to Volume and Volume to Mesh are in different menu’s and the Search can really help you (and me) out.

Mesh to Volume is in Mesh > Operations > Mesh to Volume.

Or you could type: SHIFT+A, M, O, V.

Hi @spikeyxxx, Mesh to Volume doesn’t show up for me…

EDIT: I know that my node editor is on a volume, but it doesn’t work on my mesh either…

Well Rob,

That is because you are using a rather old Blender Version: 3.0

In less than a month 4.0 is released. 3.6 is the latest stable release.

If you can’t use that (due to Hardware or so), I can find out when this Node was first added…it’s been around for quite a bit.

[Martin Bergwerf]

Okay, found it.

It was introduced in 3.3 LTS.

Thanks for all your help, that’s exactly what I was looking for. To anyone else following these steps, you may notice that you cubes all bounce inwards when they hit, for example, a plane. This is because the object origin is right in the middle of your shape. To fix this, select all of you voxels, and in Object mode, head to:

Object>Set Origin>Origin to Center of Mass (Surface)

Thanks!

[Martin Bergwerf]

Oh right!

I forgot to mention that…Thanks Rob!
