Cell Fracture Shards error?

Hi, I`m pretty new to blender and are going through a bunch of tutorials.

I`m using Blender 2.72 Cycles render engine

Cellfracture_Test.blend (1.8 MB)

I`m having som strange behavior in the Cell Fracture addon,

This is how it look like after Fracturing in the Viewport.


and this is how it looks like after rendering??
the material of the shards seems to disappear.


Could some one please help me?
What am I doing Wrong…

Hey … just to be sure, what’s the problem? You expected black inside the debris?

Hi, Thats what Im trying to achieve:)
But I may do something wrong…

Hi,Yes i want a different material inside the debris, but i can`t get this to work.

when you fractured, you told it to use material slot 2 for the interior faces… but you didn’t actually assign a material to slot 2! :wink:

fastest way to resolve it now that you’ve got a bunch of shards is to pick one, create a material in the second material slot, then shift-select the rest of your shards, and select control + L, and tell it to copy the materials.


Aha…:o I have totally overlooked this, that you can assign multiple materials to the same model:p
It now finally works!!

Thank`s for enlighten me:)
