Они вроде и так не тяжелые ( не не в том смысле ).
Это что "прорежено" по первой ссылке, где без текстур или по второй?
Глянул сетку .... Не ну я молчу. В данном случае необходимо. Это же, так сказать репродукция,цыфровая копия, так что важны мельчайшие детали. Если они, конечно, нужны.....
Это сейчас каждый музей может получить копию в мельчайших деталях...

Nefertiti is returning to the place where it was found. For the first time since the sculpture was excavated and stolen over 100 years ago, the iconic artefact will be shown in Cairo. “ “The Other Nefertiti” is an artistic intervention by the two German artists Nora Al-Badri and Jan Nikolai Nelles.
Al-Badri and Nelles scanned the head of Nefertiti clandestinely in the Neues Museum Berlin without permission of the Museum and they hereby announce the release of the 3D data of Nefertitis head under a Creative Commons Licence. The artists 3D-Print exhibited in Cairo is the most precise scan ever made public of the original head of Nefertiti. With regard to the notion of belonging and possession of objects of other cultures, the artists intention is to make cultural objects publicly accessible. The Neues Museum in Berlin until today does not allow any access to the head of Nefertiti nor to the data from their scan.
“With the data leak as a part of this counter narrative we want to activate the artefact, to inspire a critical re-assessment of today’s conditions and to overcome the colonial notion of possession in Germany” the two artists say.
