Показать описание
In this video, I quickly go over how to get cleaner looking lightmaps by tweaking a few settings inside of unreal engine and creating a custom UV channel for the lightmaps to use.

Hello! I have more of a topic of discussion than a question, but still - when i make an interior scene and go about manually overriding lightmap resolution for all of the props, at some point i seem to hit a limit and every object starts to look like it has lightmap res of 16. I set packed lightmap resolution to 4096 and don't compress it, memory usage seems to be pretty reasonable. Does something like this ever happen to you? Do i somehow hit the gpu memory limit (i have 4gb 1050TI) or is it just the fact that unreal can't pack all the big lightmaps into one and i see the result of mipmapping?
