How long should it take for a medium map with good detail take to compile?
Depends on how it’s optimized. A poorly optimized map can take 5-30 minutes to compile, while a decently optimized map can take under a minute. Here’s a good optimization tutorial.
under a minute is a bit optimistic lighting itself can take 5 especially if you lower lightmaps and compile with all the bells and whistles.
unless your just counting vvis in your estimations
