Greetings! I have some trouble with Unreal Engine 4. I've been playing around with lightmap resolution to find out what the best lightmap resolution for a model would be in order for it to look good! So I did the "Override lightmap resolution" from 64 to 2048 which is the gave me the best result for the model. My problem is that It increased my building time drastically. It went from 7 seconds to over 4 minutes, and I have a pretty powerful PC. (And I was using the Lighting Quality of "Preview"). I am currently using the 4.9.2 version of Unreal Engine 4.
If there is anyone who can help me out please type a comment!
