The noise texture doen't work at all since it's not applied to the bevel and I use the exact same value!

Hi maxcady, I think this has to do with the fact that this tutorial was done in an earlier version of blender.

Now you need to add an extra node between the Cross Product and the Mix Shader nodes so the dimensions between the output and the inputs are consistents:

Add a Length node (You will find in a  Converter > Vector Maths and pick Length in the dropdown). That way it converts the Vector (blue dot) output, which is three dimensionnal into a one dimensional input (grey dot) by taking the "length" of the cross product output (the norm of the vector would be more mathematically appropriate).

Hope this helps,

mmmmmm.... interesting.... But still doesn't work. I take the same value and it's Cycles rendered. :-( 

Can you help? It drives me nuts.

I think you need to adjust your colour ramp node  maxcady 

I changed the ramp values. It's kind of working. Thx!
