Sorry Robert, but i still dont see the point about using many shader
OP.. io just one..
I modelled an entire classrom with chairs, tables, and of course the room.
the furnitures where "grouped" by items (legs, planes, woods, metals
parts) considering the type of shaders they will host... then i applied
a single shader OP by choosing the groups and applying the shader.
in the Liza scene i see that, ok the objects are separated (they were
obviosuly) and now contains many groups (for the object parts and
shading parts).. but i still dont see why using many Shader nodes over
using just one :)..
sorry that was just a simple consideration but my english sucks and I
might be misunderstood.. I'm trying to understand and i was just trying
to understand the difference between on and more shaders SOP.
thanks for the feebback tought.
