Cell Fracturing Tutorial


This is a long video tutorial about the new voronoi cell fracturing tools in the new Blender 2.64 test build.

Daniel Kreuter writes:

This video contains:

  1. Information about how to activate the features
  2. A demonstration of what it can do
  3. An explanation about almost every single value
  4. Experimental examples of what this tool can be used for

The Cell Fracturing tools were integrated into Blender just a few days ago and I couldn't wait to make a video about this features. Of course it took me a while to get familiar with all the new values but I think I understood most of it now and I'm doing my best in the video to explain all I know.

I hope you'll enjoy watching this video


  1. Philippe ROUBAL on

    Great new feature, and very useful video ! Thanks for sharing. Breaking things will be much easier !

  2. I wonder how well it looks on objects with smooth shading? Does it conveniently sharpen the normals near the edges?

    More broadly how are normals treated after fracture?

  3. The grease pencil line that allow to cut the model in 2 with the cellfracture seesm to be a nice knifing tool.
    But in the video, the model is not cut where the grease pencil stroke is made, it looks like it cuts in a completely different direction ?

    • The grease pencil line itself was not used in the calculation.
      The grease pencil line start and end points are what is used to create points.
      The fracture plugin creates a cell around these points and where these cells meet a fracture is generated.

      • John D Smith II on

        It looks like the points in the line tell Blender where the pieces will go, not the cut itself. Kinda the opposite of the way the knife tool works. It seems to cut along the lines "normals" ,so to speak, with the point itself being the new pieces center of gravity. Thats how it looked to me anyway.

  4. Something similar for the Game Engine would be awesome! I can just imagine a FPS with bits of brick and wood splasing all over the place when you shoot at a wall or a tree

    • You can do that already :) If you understand German (or at least just watch) I know a tutorial from
      He is workind with the old fracture-AddOn, but when he program the GameEngine, it is pretty the same.

  5. This is not only awesome for animation, but this looks very promising for destructible environments in games! Now, if we just get the Android support for BGE, as well as alpha-enabled shadows and built-in water shaders...

  6. Wow, awesome! Part 1... does that mean there will be more!
    Thanks a lot for this, it really helped. I cant wait till bullet physics gets integrated into non BGE so that we can do this real time.

  7. Where did you learn how to use fracture, I would like to learn all there is to know about Blender and can not find any full training for it, not even through buying DVD training
