Lightmap encoding high quality


When I try to convert my project from normal quality to high quality (lightmap encoding) Unity starts to work, but it takes hours, and then it freezes, using 99% of memory and CPU. Is there a way to avoid this? My project is in Unity 2017.3.1f1 and everything is working perfect.


Solved: now it crashes before finishing.

I have the same issue. It keeps on crashing right after starting and I have a really good PC. I don’t know how to fix it.
