Thanks a lot Robert.. wow now that's cool..
ok.. I have another question then.. about takes...

I'm playing around with take from which i'm "including in take" some 
parameters like sufaces colors.. and so on.. but on some shaders (like 
the "filmcan6" (by CTRL+LMB click) ).. when i try to include the Diffuse 
color (which in this case is a sort of blue) instead of giving me free 
sliders to choose color it links such channels to 
ch("../../vmetal1_diffr") (and blue and green) .. while on the table 
this doesnt happens).

and related to this.. where ch("../../vmetal1_diffr") points at? i dont 
see any "vmetal1" vex shaders actually from the SOP network .. but i 
might be confused and looked at wrong place.. dunno.

Hope i've been clear enought.. my english sucks sometimes :)

and at last.. I dont get why if I change the reflection color (of same 
materials for examples but on the table as well) this dont makes any 
changes... i tried a bright red but i see no reflections...

cheers and thanks a lot for the fast support.
