Houdini | advanced boolean fracture - by consolidating small pieces

In this tutorial we are developing a tool that we can use to remove very small pieces that often occur when using the Boolean Fracture SOP.
As the algorithm is strongly parallelized, the tool works quickly and reliably even with complex geometry.
Graph Coloring is used to make this possible.
You can find more information on this topic under the following link:

You can download the tool at the following link:

I had a problem will big pieces merging with each other. Turning off 'Refine to Connected Manifold Pieces' inside the measure node fixed the problem for me.

Thanks so much for the detailed guide!
Perhaps, to facilitate the search, it is worth adding houdini to the video topic, for example, "Houdini advanced boolean fracture - by consolidating small pieces". Possibly more interested people will see)
Hashtags probably won't hurt either) #Houdini #SideFX

That is a very good point indeed! - I'll do that.

i was wondering if it is possible to get chipping and have it slowly have the smaller chipping pieces fall first like wtigh the rbdmaterial fracture

Video is great! I am running into an issue however, where my pieces disappear as my minSize goes smaller(below 0.3). As I increase my minSize the pieces re appear, but they don't combine together as they should. Instead of a cube I am using the rubbertoy test geometry.

Thanks a lot.
Did you download the tool or did you do the tutorial? If it doesn't work with the tool that is available for download, feel free to send me your hip file and I'll have a look at it.
You could also try scaling the geometry before sending it into the tool. A factor of 100 or 1000 should be good. After the tool, you can then undo the transformation.

Sir why u not making video on houdini
