Hello everyone!
I have made a building using modular assets. Then I merged everything in one piece so it is easier to transfer mesh between projects or even different engines. However I just noticed that interior is a lot brighter in a new mesh:
Probably need to take a look at the lumen scene view under lit. Lumen uses a limited number of cards per mesh for lighting and when you merged actors, you probably are getting less cards to represent the lighting well.
Thanks, I will take a look at it. However I dont think it is an issue with lumen. You can see the same situation with lumen disabled
Just checked Lumen scene view, and yes, the mesh on the right just disappeared. I tried increasing lumen mesh cards in mesh settings to 32, but nothing changed. Do you have any another ideas?
