Like you can see in the title, when i try to build the light my entire PC freeze and it’s a real problem because i can’t have a final result and make my pc slower, i don’t think that can be come from my PC but i’ll give you my spec :
It’s normal for the process to grab a lot of system resources and in some cases best done when you don’t need the computer.
If it completely stalls your machine, a likely culprit is when people turn up the light map resolution too high and/or have an insane amount of light sources in their scene.
No, no. It freeze when there is a minimum asset on the scene, when it’s empty i can build the lightning. But in my level a bit big with Redwood i cannot build whitout freeze, but i see a post on the answer hub who said if i put the light to movable it will resolve the problem, clearly i dont know why but i was able to do 2 consecutive build so i tried to do the same in another project, i put the light on movable but this time, freeze at 88% so i return to my previous level (Redwood) and again, freeze at 89%
“Lightmass will Crash if it runs out of memory. This is often reported as a bug, but it is simply a limitation of your system setup”
Although I’m not entirely convinced that this is what is happening to you.
Maybe you can try to further optimize the scene, so turning down light map resolution of your objects and placing lightmass importance volumes
