I am trying to apply cell fracture to my house model. The model looks like here: enter image description here

When I apply the fracture, the model becomes enter image description here

And here are my settings which I am using: enter image description here

Does anyone has any idea what's going on?

  • $\begingroup$ Well, the second picture should be exactly the same as the first one, i.e. on the second case fractures and cracks should be made along the house walls, not changing its geometry! Only when I simulate it should start changing, but the initial geometry should be identical to the original mesh $\endgroup$

  • $\begingroup$ If you rendered the geometry in the first picture and then that in the second picture, you shouldn't be able to see a difference. It only looks weird in the 3D Viewport. $\endgroup$

  • $\begingroup$ Well, I am not using rendering, as I only use Blender to export my models back to Unity. So I was kind of trying to reproduce house demolition animation and export every animation frame into separate fbx file to recover demolition sequence. But if geometry is changed, I suspect that it would not be looking as a house anymore... $\endgroup$

  • $\begingroup$ Perhaps you should ask your question on a Unity forum or an .fbx file forum? Also, why use Unity? Blender's built in Game Engine can simulate that demolition just fine. There is a two part tutorial on it. Part one can be found here. $\endgroup$
