I'v tried to build tower from single stones After few hundred my mac said - "Stop you supid bastard! and restarted modo without saving :/" So I decided to make simple model. The first ide of creation was to make some models that could be used on your maps, so there is no need to make high detailed model because in final work on map the tower or the mill will be no bigger than 1-2cm i think anyway you are great people with your knowledge and help. Thanks to you i want to learn more and more about 3d modeling and texturing
