Hello Robert,

First of all, you're explanations were very clear about the dynamic 
workflow related to the SOPs.

Well, I chose an other way :
I kept only one leg from the for ones, placed it at the origin, and 
create the dynamic legs with "Number of Objects" in the "RBD Object".
I then transform them in this DOP (see details on previous mail).

Is it a wrong way ?

If not, why do I lose a leg when I put the dynamic legs in a "Merge" DOP 
? I made the same network as at the end of the 4th page of the tutorial, 
except my rbs_tablelegs node is set as described above.

That makes sense.
