I am making a large 128x128 quadrant level. I have an i5 7600k, gtx 1080 and 8 gigs of ram. Wherever I try to build the lighting for the level the computer crashes. I have no idea what to do now. Please help.
You need more ram.
Approximately how much more ram? Is there any other way to solve this problem? Your help will be greatly appreciated
But if the level is too big then you shouldn’t use baked lighting and instead use dynamic lighting. Many games have to do that.
Static lighting means each static surface gets assigned an unique texture area in the light maps. If your level is large enough (like your “128x128 quadrant”, whatever that means), it might require more light map data than can ever fit in your (or anyone’s) RAM and you should consider using dynamic lighting.
I’m really a big noob here. Just started out. Can someone tell me what dynamic lighting is and point me to some good sources on how to use it?
read the docs Lighting the Environment | Unreal Engine Documentation
i think he means 127x127 quads, and at 1x1 sections that would make the map size 1kx1k and 2kx2k if he used 2x2 sections. thats a pretty small map to be having problems building light, even with only 8gb ram. im assuming he has not put many actors in it yet seeing as this is the first time building lighting
Also, check lightmap densities(use the viewport visualization to check). That can make your ram usage explode quickly.
