No not exactly, becouse for example as you can see in my last work I mean spider, it has 4 legs. Each leg consist of a lot of objects. And if I export this leg the same object on diffrend leg will have diffrent name. For example I have some panel wich is the same on every leg, but it will have diffrent name. And when I assign material in the render software I have to assign it to each panel individually. When these details a lot I have to spend a lot of time assigning this material. But if pannel have the same name on each leg I have to assign color once.
