Fbx to 3dsmax: texture export advice

[barrubba]

i need to export fbx to 3dsmax for rendering. It's a interior church survey, 12m total height)
can Generic, average, 8000x4 give me good sharp texture?
(64gb ram, gtx 1060 3gb)
i'm exporting multiple piece of mesh, and at the end, importing all in a single max files..
it's a good workflow?
maybe some parts will be coincident and would need some mesh editing
