I'm breaking a sphere and using the cell_fracture add-on to break into pieces but when fracturing:

building blocks

buiding blocks don't dissapear...

How to avoid these blocks to remain after the simulation?


Applying scale and rotation CTRLA don't solve the problem..

    $\begingroup$ If you mean that you'd like to make sphere continue being sphere after fractured then try applying scale via Ctrl+A menu. See blender.stackexchange.com/questions/7298/… $\endgroup$ – Mr Zak Mar 6 '16 at 20:03
  • $\begingroup$ it didn't solve the problem.. but I found out why this was happening: normals! The affects the 'breaking side' ;) $\endgroup$ – Francesco Yoshi Gobbo Mar 7 '16 at 7:13

    $\begingroup$ It solved problem for me. Applying scale (which in case of this sphere is negative) flipped normals and set scale to 1. After recalculating them I got correct fractures. This allowed normals of sphere to be pointing correctly (outside). $\endgroup$ – Mr Zak Mar 7 '16 at 9:44
  • $\begingroup$ You are illuminating me..! I missed the negative scale! After all.. they are synonymous I suppose :) $\endgroup$ – Francesco Yoshi Gobbo Mar 7 '16 at 10:16

    $\begingroup$ I'd say the scale > normals > fractures are cause and consequence. $\endgroup$ – Mr Zak Mar 7 '16 at 10:55

Normals influence the breaking side.

Flipping normals to the inside SHIFTCTRLN solves the problem!

(in edit-mode before launching the cell-fracture add-on)
