Unity High Quality Lighting Tutorial (Part 2) 

Thanks for the tip. I've haven't worked with the linear color space (never found it necessary yet). I'll have to do some research and testing. If it's as good as you say it is, I might tweak the lighting to use it for the final build of the game.

Something I didn't cover in this series (which I really should have, looking back) is the lightmap resolution per object. If you select a mesh in your scene, in the Mesh Renderer component, there should be a lightmapping section and within that, there is a parameter called "Scale in Lightmap". For all objects, this defaults to 1. If you want and object to have a lower lightmap resolution (say it' farther away or not very important), you can reduce that number. For large environment pieces, I'll drop it down to 0.2 or even 0.1 if it's really big. That could help reduce bake times. Realtime GI doesn't bake as much information so it's generally faster, but to my knowledge, all light baking is done on the CPU. Even if you have a very nice graphics card, it won't help. If you're using a 7th generation i5 CPU, then you don't benefit from multi-threading, (I believe the 8th generation introduced multi-threading in the i5 processors) which will drastically increase your bake times. I use an i7 3770K which is a few years old at this point, but the multi-threading than an i7 provides over an i5 is immensely helpful.

AlienMinefield I was really stupid to buy i5 7400 then ryzen 1500x and light map bake Everytime I make little changes in scene and then another half hour of light map baking Well Yeah Thanks alot for help,it's means alot to me
