$30,000 of Pro Assets (Or Game Credit) to trade for Rift VR Blueprint help/info

After doing my first Lighting Build, (then making them static and doing it again, LOL
I got: "“no importance volume found and the scene is so large that the automatically synthesized volume will not yield good results. Please add a tightly bounding lightmass importance volume to optimize your scene’s quality and lighting build times” WHEW! LOL
So, I was out there looking and you are right! I found: “no importance volume found and the scene is so large that the automatically synthesized volume will not yield good results. Please add a tightly bounding lightmass importance volume to optimize your scene’s quality and lighting build times”

I was just looking for some info and found:
“WTF Is? Volume - Lightmass Importance in Unreal Engine 4”

Imagine me with steeple’d fingers saying: "Ex-el-lent! (like Mr. Burns LOL) THANKS! All this great info, it’s out there when you need it! it’s amazing, THANKS AGAIN!
