Hey all,
I cant get the GPU lightmass to build with anything but default world settings. I set the indirect lighting bounces to 20 but it will only ever do 3. This happened after i split the level into two separate levels to use level streaming. It was working well before I did this. Has anyone had this problem and know a fix? See the image below. The radiosity pass used to do 20 passes now it will only ever do 3.
Also i’m building the light using this command to save memory if this might be the cause?
You can use command line to launch the editor and bake lighting to save GPU resources for GPULightmass, especially video memory.
- Engine/Binaries/Win64/UE4Editor-Cmd.exe “path o\your\project\yourproject.uproject” -run=resavepackages -buildlighting -allowcommandletrendering -map=/Game/Maps/MyMap.umap
- Remember to replace Content with Game in the umap path
