My problem is the following:
I got this error:
Performance Warning: No importance volume found and the scene is so large that the automatically synthesized volume will not yield good results. Please add a tightly bounding lightmass importance volume to optimize your scene’s quality and lighting build times.
So I placed a lightmass importance volume, and covered with that the entire landscape.
After this, I get this error: (image attached)
WorldSettings_1 Maps need lighting rebuilt
I didnt found any solution. please help me what should I do
