It's a remake, not a remaster in the definition that you are thinking of. Vicarious Visions did not use any of the code, likely to the fact that either it was unusable or they did not ever have the source code.

N. Sane was done in Alchemy Engine, not Unreal Engine 4 (unlike Reignited), although VV is likely following suit with their upcoming project.

It's likely that Vicarious Visions was unable to get the source code from Naughty Dog due to Activision being unable to get it via Sony, though I'm not 100% sure about that since VV mentioned that majority of the original code is virtually unusable in a blog post.

For those interested about the mesh level geometry, you can give the SDCC 2017 panel a watch.
