i have a scene with over 1500 objects in, all these objects have a material that changes color when one of the objects rotates. i used a driver for the diffuse channel and set it to z rotation in the driver variable. i have then made the material for all the objects as single users so the rotation only effects the material on that object the only problem is the variable ob/bone option does not stay relative to the object and manually going through and changing each is a head ache. is there anyway to make the variable relative to the object when copying or through the use of a script.
any help is much appreciated
