Hi,
I am modelling modular sections of an urban environment that I plan to lightmap. I am new to UE4 but aware that ‘leaking light’ is often an issue. I know from previous experience with other engines that building meshes with thickness, and no holes (making sure to include backfaces etc) can often reduce or eliminate such problems. Is this also the case in UE4? Of course, I’d rather not include backfaces because of overdraw and whatnot, but I also want to avoid lighting problems and it’s obviously pretty important that I make the right decision upfront.
Any help from someone with experience doing this would be incredibly helpful.
Thank you,
