Can't render Cyrillic text from .tex file

I’m writing on Cyrillic in Scrivener 3 (Win beta version) using included non-fiction LaTex template. When compile, Cyrillic letters are just white blank spaces.
Probably, there is trivial solution to the problem, but I am n00b in LaTex, so need your help.
Thanks

Have you tried using XeLaTeX to typeset the document? Generally speaking it works better with Unicode, and it allows for the use of system fonts, so you have more options there as well. There are ways to stick with pdflatex, but you’ll have to add some packages to the preamble—the one I’ve provided is pretty simple so it is easier to modify to what you need.
