Cell fracture producing warped faces I have a plane that I have been trying to fracture (similar to the way glass can break).  I used the grease pencil and solidify modifier with the default settings. 

For some reason, when I use cell fracture it causes the faces of the shards to have convex surfaces rather than flat like the plane had.  How do I get them to look flat?  I tried using the debug boolean option which produced the look I want, but the shards seemed to disappear into thin air when I apply active physics to them.

Here's the pic of my results:



These are my settings:



Any help would be greatly appreciated!

Here is the .blend:
You could try out the Fracture Modifier Build.
Make sure to use the &quot;latest development build&quot;, or just use the more recent graphicall build.
I also had to edit 3 points or so of the greasepencil strokes, because the FM (fracture modifier) created some holes in the mesh there (points were too close to each other)
For the simulation I made the bullet a trigger and the plane animated and triggered. Furthermore I played a bit around with constraints.
