Mass of shards with the the cell fracture add-on Using the cell fracture add-on I create shards of different sizes, and I want to use them in a rigid body simulation. I have the option to set the mass of the shards based on their volume:



The problem is that I don't know how to access these masses. The shards don't have rigid body physics activated, and if I activate rigid body physics on them, then their mass will be the default 1.000, independent on their size.

I saw a tutorial where the guy went into "Blender Game" mode, and indeed if I do it, I see the expected mass values on the shards. But I don't want to use "Blender Game" - I am not interested in game development. I would like to have these masses with Cycles and normal rigid body physics.
This setting is located in the properties panel>physics>rigid body tab.




You may also go to the tool panel>physics tab, (while in object mode) press T if it is not open already. Select calculate mass, and Blender will give you a host of preset values such as broken glass, iron, cardboard, etc.
