Hello! I made a map with a similar mechanic where zombies got tougher at night, and I wanted a smooth transition as going between day sequences is very sudden and the blend settings don’t do anything. The total length of a day in fortnite is about 18 minutes (45 second hours), I made a sequence that is 1063 seconds long. Set sequence to play automatically at the start of the game. Then set your day sequence to start at 22 hours, as this is the beginning of night time. You can then set a marker 515 seconds into your sequence which will be when daytime starts. This sequence is now your whole day and now you can put triggers or other devices in there to activate at certain time! If you’d like to try the map it is 5152-8352-0052
