just wanted to share a little script i wrote recently. since it's using SOuP i thought it might be a good idea to post it here as well.
the tool can fracture (flat) objects by a voronoiTexture3D or a custom image. it also uses the "split mesh by object group" feature from SOuP.
some other stuff like mesh cleaning, auto-extrusion and center pivots of resulting chunks are integrated as well ...

you can download it at creative crash:
http://www.creativecrash.com/maya/downloads/scripts-plugins/dynamics/c/voronoi-texture-fracture

hope it's useful to someone.
cheers! :)

thanks - glad u guys like it! :)
thought about putting the point cloud fracture stuff (scatter & shatter) in there as well, but don't really have the time for that atm ...

just uploaded a new update, mainly because i ran into a problem using the "split mesh by object group" after TextureToGeometry conversion. somtimes pieces would just disapear.
i ended up writing a procedure, which splits the mesh by shaders (thanks to Jean Delaunay on this occasion for pointing out the issue and suggesting a possible workaround) - so the problem is solved.
however: any ideas why this (disappearing parts after split) was happening?
i'm just curious and was wondering what exactly the feature is doing or what's the difference to splitting by shaders?

next up might be an option to paint a fracture pattern directly onto the mesh (via 3D Paint Tool) and/or integrate the scatter and shatter workflow into the GUI. anyone interested in these features? just let me know & I'll add this stuff asap ... cheers! :)

// Error: Specified file default/sourceimages/voroShd_vtf_fractureObj_tmp_tmp.iff does not exist

@peter:
script is sent.

@jeremy:
thanks for the feedback & sorry it didn't work for you at first attempt.
you might just have to set a project for the script to work because i currently query the active workspace to find the source images folder. if that's what's causing the problem i could change the location of the fracture images to some place in the user directory to avoid this error, when no (or default) project is set.
i attached a version with the changed directory. let me know if that works for you. cheers!

just updated the script on creative crash. fixed the bug that occurred when no project was set. if "sourceimages" is not accessible a custom folder in the user dir will be used  now.
also added a settings menu so users can specify where they want the file-converted voronoi textures to be stored.
hope it works for everyone now. :)

just source the script.
usage is described on the download page like this:

USAGE:
- create a poly plane & add it to the GUI
- click "Create Voronoi Shader" button OR choose an image as fracture source
- adjust other option as needed
- click "Fracture Geometry"

there really isn't not much more to it. all the check boxes do what their label says. just give it a try ;) ...
