  4. Hello! I’ve set the add-on, but it doesn’t work. I switched on “Cell Fracture”. But any way it unworkable… What version of the Blender works with this add-on? Thanks in advance!

    • Hi Paul, thank for trying this addon. The addon is developed in Blender2.77b, so I recommend using it in 2.77b.

      And can you find “Crack It” panel on toolshelf as tutorial video shows? If the panel doesn’t exist, “Crack It” addon seem to be not activated.
      So please make sure to enable “Crack It” addon and “Cell Fracture” addon, and click “save user settings” in “Addons” window in “User Preferences”.

      If there is “Crack It” panel but doesn’t work even in Blender2.77b, please let me know more detailed condition of the error.

  5. I’ve tried several times to install to Blender 2.78, and though the User Preference reports it was installed, and it IS in the Roaming/ directory under addons, it does not appear as an option in Blender’s User Preference list of addons. I’ve enabled Cell Fracture, hit refresh, still nothing. No errors reported by the console. Thanks in advance for your help.

    • Hi, bobnolin. Thank you for the report.
      Crack it addon should be named as “Mesh: Crack It” in Mesh category in User preference’s addon panel.
      For test of your report, I downloaded and installed crack-it addon in Blender2.78a and 2.78b. And it succeeded in Mac OSX Sierra.
      So, please see if crack it addon appears in Mesh category, or place an unpacked crack-it folder (including __init__.py, crackit.py, and operator.py) in correct addon folder for 2.78.
      And if it don’t resolve the problem, please more information, such as screenshot of user preferences panel, and OS.
