I have finished a scene, and the lights were all movable at first, then I want to test static lighting for the same scene.
So I cloned it. Then I change everything to static, the meshes, lights are all static now, and when I started to build lighting, every time it got stuck at 99%, in Swam Agent, it showed that lighting build was complete, but it didn’t export result or finish it. So I though there were problems with my meshes, then I started to delete meshes from scene.
Every time I deleted a mesh from scene, I tried to build lighting, however, no luck there, the strange thing is, at first, Swam showed me it stuck at 99.43% when I deleted some of the meshes, it showed me it got stuck at 98.40%. Each time after I deleted some meshes, the percentage got lower, and I don’t know why that happened.
The weirdest thing now is that I have deleted everything in my level including lights, meshes, decals, sound cues, and I placed a fresh new directional light to test, but build lighting still got stuck at 50%. This is too strange for me, the scene now is just a empty black space with one single directional light and it cannot build light.
Another thing is I did test other project using 4.9 the same version as I used to create my scene. I just opened it with starter content and placed some chairs and a light, it can build lighting successfully. So it is may not the problem with engine, but my scene is now empty, but build lighting still get stuck, I don’t know how to make it right.
