Hi to all. The editor is building the lighting of my project, and it has been stuck at 99,52% for more than 24 hours long (light building started around +40 hours ago). Swarm Agent seems to be working, but I don’t know if rendering it’s going to be finished in a reasonable time or if I should stop it and restart it with other lighting settings.
The scene is semicomplex, with a big ammount of repeated assets, expensive shaders and high resolution lightmaps, but it’s not something out of the ordinary. The scene has a lightmass importance volume and is being lighted by a single stationary sunlight. Lighting and world settings are set exactly in the same way as shown in the showcase Berlin flat.
I built the lighting in this same scene with the same settings as I was starting the project and with a simpler environment, and it lasted about 10 minutes. So I don’t know why it’s now stuck for more than 24 hours at 99%. I mean, even raytracing would have been faster, so I think that, either I’m doing something wrong or that’s a software bug
Advanced thanks.
