With Renderman in Maya, one is able to change a texture map or an attribute based on the name of the object it is applied to. In Houdini, this is done on the material node by adding local overrides. The user can alter any attribute on the chosen shader based on a group or on a stamped copy number.
Be careful when changing texture maps. These are passed in a strings rather than floats or integers so proper formatting is key:
`"/path/to/file/filename" + number + ".tex"`
Now the user can alter the number so that filename1.tex, filename2.tex, and filename3.tex are all accessible by the same shader and material node leading to quicker render times!
