Small levels work fine, but in a big open world level as soon as we enter the play mode (in editor or a separate window) all shadows disappear. It used to work but then this started to happen. We tried to build the scene, it doesn’t seem to help.
Hey there @anonymous_user_e3758472! Could I see an example of the map and the shadows missing? You say it’s all shadows right? I’m inclined to believe this is either a level streaming or world partition issue but not quite sure.
Are you using world partition or level streaming?
Also may I see the settings on the sky and directional lights?
