Hi, I’m a UE beginner and I downloaded and looked at Isac Crawford’s abandoned apartment demo.
At first, light build and shader compilation took a lot of time, but after completion, they were able to navigate through beautiful levels at 15 to 20 fps.
I added an asset that I made myself to the level for practice. Then a message was displayed at the top left of the viewport saying that a light rebuild is needed for one object.
I ran the Build Lighting Only command and it looked like the UE was rebuilding the light for the entire level. I expected the light to be rebuilt quickly because only 1asset was added, but it didn’t and it took a lot of time again.
Q: Does the light rebuild target the entire level originally? If not, is there an option to rebuild for only 1asset?
