Importance volume can really change build times and quality, so put that in.
But the UV messages, don’t worry about them unless you can actually see something wrong with the meshes.
The Meshes seem to be alright it just takes alot of time to build and I havent done any game functionality in the world yet so I was wondering if it would cause any issues in the future
If it takes a lot of time to build ( lot of time being between 10 mins and a few hours ), then you probably have one or more of
-
Lots of meshes ( > 2500 )
-
High density light maps
-
High quality settings ( non default ) in the static light settings of lights.
-
You’re building for production, not preview
