Out of memory issues

@John_Alcatraz

You pretty much need at least 16GB to be able to use UE4. Sure some things work with less than that, but it won’t really be fun, especially if you use static lighting. Even when I had 32GB of RAM I often had that being completely filled while using UE4 + Chrome. Only when I upgraded to 48GB of RAM I no longer had issues with it, so 48GB seems to be “enough” for UE4.

Hi @John Alcatraz!

I’m currently deciding whether to go full dynamic lighting or offline lighting for my game.

I was under the impression that, UE4’s offline lighting solution/ bake lighting can be very time consuming but not memory consuming (compare to packaging).

48GB of RAM just for baking light…seems like an outrageous amount of memory to me, may I ask how large is your map and how many actors are there in the map? (and perhaps your lightmass importance volume setup?)

Thank you.
