2 sided materials
imagine 1 plane with 2 sided material, I want to know when light baking on this plane, what will result? ue4 creat 2 lightmaps for it or one side going to be dark and one side will get light information? Thanks .

the light will be baked on the non-backface side, and applied to the backfacing side. there is an option to allow lighting bakes on both sides, but they get mixed together as one.
its probably better to just make a very thin mesh in case you need shadow/light data on both sides.
