VoroFrag is a free modifier that allows to make voronoi fragmentation. It handles convex and concave objects, as well as hollow meshes and open surfaces. It offers a "Box Mode" for quick fragmentation. Support for mapping coordinates, material ID and normals.

Recompiled for 3DS Max version 2017 to 2021

Problem Solved

Thanks for the quick response. I double checked all of my polygons, and noticed some strange overlapping polygons that weren't supposed to be there... So I simply deleted them, capped up the mesh, and everything works perfectly fine.

Hi DavidAnatolie,

Thanks for using my free plugin and I hope you like it !

FYI, the updated version 2.5a is only for Max 2015, so the other files are still in version 2.5

Next, be sure that your base object (before any modifier) is closed, because VoroFrag doesn't create volume in opened mesh (like the teapot).

Does VoroFrag create volume on your object when the "gap width" is small or null ?
If yes, could you check at which value does the problem happen ?
And maybe also try to change the "seed" value.

Finaly, if the problem persists, you could send me by private mail your object in a Max file compressed in a zip. I will try to find a solution.

Issue with VoroFrag 2.5a

I have an issue when using this (v. 2.5a) using Max 2014. Basically I have a wall that I unwrapped. After the unwrap modifier, I add vorofrag. The standard mode works well; keeping my UVs intact and giving me the ability to adjust my inner faces mapping. However, the problem exists when I increase the "gap width" setting in that it does not create volume for my frags. This forces me to use "box mode". Now, I lost all my UVs and I don't have access to the inner face mapping parameters which I need. Interestingly, the "gap width" works well here; creating volume for my frags. Any thoughts?

Update 2.5a for 3ds Max 2015

- Compatible with 3ds Max 2015
- Minor optimizations

Note that this is not really a new version.
The minor optimizations only concern 3ds Max 2015.
A new version with new features will come later.

Thanks for your comment

I appreciate your comment and the referencing on your own blog.
This plugin is still developed, as well as two other projects that are in beta-test.

For some reason the 2.5 would not work with my 2013 32x. Other than that was no bother at all and works perfectly.

Awesome feature in v2.5 must say.
Keep up good work

Update 2.5

From the change-log:
- Fragmentation enhanced on complex concave meshes
- Animated parameters work now as expected when the plug-in interface is unloaded
- After detaching the fragments, the normals are now preserved
- A new option allows to directly detach the fragments in a separate layer with a custom name
- An issue with the world coordinates and some imported objects is fixed
- When moving or animating an external objetct or particle system as "custom particle",
the plug-in is more responsive and now recompute correctly when the plug-in interface is unloaded
- The parameter changes on the rollouts "Detach params" and "System"
do not force the plug-in to recompute unnecessarily
- The pick button "pickPFlow" is now correctly exposed to maxscript and works as expected
