Hello everyone!
This is my first post on this forum. We’re a team of seven students and we’re still discovering UE4. Because our map is pretty large and we have external constraints, we must use the “world composition” to split it in several sub levels. We decided to put all the lights and post process on a specific sub level without anything else. Every time we try to build the whole thing, UE4 crashes during the light build and give us this crash log:
Access violation - code c0000005 (first/second chance not available)
