Bug Lighting Help / Bug Report

The Bug, Once I've baked my realtime maps and then closed the project I can't open it again without a crash occurring and the project won't open again until I delete the generated lighting file, the file itself was about 2.6gb in size.

So I would like to mainly use Real-time Global illumination in my project and most of my scene currently looks like this in UV(contribute/recieve) mode. with a lightmap scale for a lot of items being in the 0.01-0.05 range. Is this ok or do I need to change this up a bit? The world is based on a 1000x1000 terrain with 1/3 of it used. Is it best to cut out the unused section(big hole) or leave it as is performance wise?



Also when I try baked lighting it looks awful for the most, how would you best tweak those settings to suite an open world?
