UV's for light maps

I haven’t tested automatic lightmap UV generation in UE 4.5 yet, but if it works as describes I need to check this out asap

Definitely try it out! It’s actually quite intelligent now (most of the time)

Simply flatten mapping my uv’s never gave me good results tho. Not too sure how you end up with clean, accurate shadows by doing it this way. Usually we would need to have as less uv islands as possible, placing them carefully , etc. That what is time consuming to me… Maybe i’m trying too much to get perfect shadows (or i’m utterly bad, it’s quite possible hehe) but when you come from offline rendering it’s hard to adapt. I tried many times to unwrap a high poly chair and there was ALWAYS something wrong once imported in UE4.

Strange, whenever I tried to flatten my walls or ceilings or floors, it never really worked properly. I flattened some furniture and it generally works out pretty well, but for the most part I’ve relied on the auto UV’s lately unless it stuffs up.
