Hi everybody,

I have made an assembly of clumps using clump templates. There are some atand-alone sphere and of course some walls in the model.
I have difficulty in assiging different colors to each type of bodies(clump, sphere and walls) in the model. It seems that the IDs are very polluted.

In a very simple script as follows when I try;

for i in O.bodies:
         if i.isClump:
             O.bodies[i.id].shape.color=(.1,.7,.9)
         else:
             O.bodies[i.id].shape.color=(1,1,1)

Changes the color of all bodies (yes, including the wall) to  (1,1,1) means that it does not consider them as clump members. 

Any idea? What's going on here?
