+ The addon makes a cracked object based on selected object. Also you can use material preset for cracked objects.
+
+ WARNING1: Please enable 'Object: Cell Fracture' addon before use the addon!!
+ WARNING2: Obejects which have many vertices or complex shape could take huge amount of time to make crack.
+ So I recommend using simple object, or simplifying object by applying decimate modifier in advance.
+
+ Besic Usage:
+ 1. Select an object.
+ 2. Find the addon's location in create tab in the toolshelf left. It's usually the same tab of 'Add Primitive'.
+ 3. Click 'Crack It' button. It makes cracked object with some modifiers.
+ 4. Tweak modifier setting. Decimate modifeir to simplify shape, Smooth modifier to smooth shape.
+ 5. Select material preset and click 'Apply Material' button.
+
+ Crack Option:
+ 'From Child Verts': Use child's vertices and position for origin of crack.
+ 'Scale X/Y/Z': Scale of crack. To make long crack like bark of tree, decrease scale of an axis.
+ 'Max Crack': Max number of crack. Notice that if you increase it too much, calculation will take long time.
+ 'Margin Size': Margin of crack. To make more gap of crack, increase it.
+ 'Extrude': Extrusion size along with object's normal.
+ 'Random': Randomness of crack' rotation and scale.
+
+ Material Preset:
+ 'Excrement': Poop/shit material
+ 'Mud': Mud Material
+ 'Tree': Tree Material
+ 'Rock': Rock Material
