Memory usage issue

Hi guys,

I am using UE4 making a arcviz project, and when I build the light, my memory usage went up to 15.9G of 16G of my PC. And I upgraded it to 32G, rebuild again, it went up to 30.5G again, version is 4.11. anyone has the same problem?

Your scene meshes are proly too high poly; baking will take a lot of ram.
