Church of the Transfiguration

RUS:
Храм отсканирован. Дважды. В первый раз удачно получилась нижняя половина, но отвратительно — верхняя. Во второй раз — наоборот. Посему пришлось собирать модель по кусочкам, заодно выполняя ретушь в Substance Painter.
По моим прикидкам на работу ушло не менее 9 часов. Возможно, проще было смоделировать вручную?
ENG:
The temple has been scanned. Twice. The first time the bottom half turned out well, but the top half turned out terrible. The second time it was the other way around. Therefore, I had to assemble the model piece by piece, at the same time performing retouching in Substance Painter.
According to my estimates, the work took at least 9 hours. Perhaps it would have been easier to model it by hand?
