A few people mentioned the UI acting up. I just wish I could reproduce it. I'll look into it some more tomorrow.
The lighting isn't built, you're right. The lightmap resolutions are leading to some really weird looking baked lights in some areas. I'll try to disable the text
You mentioned lag: what are your computer specs? We are aiming for 60fps+ on a gtx 1060+, although we dip into the 50s a few times when testing here. If you are getting bad performance with an equal or better card, let me know and I'll optimize things better. I think its draw call bound at the moment, so that means some research about hierarchical instanced static meshes this or next week!
