Dear Community,
I have been stuck with this problem for a while now. The problem I’m having is that suddenly after no particular large changes, my editor suddenly started to load my main level very slowly, it takes about two hours to load in. I found out that it might have something to do with the lightmass calculation, because when I build I seem to get this error from my Swarmagent.

The game still runs, the editor does too, but everything is just incredibly slow, it is really hindering my work. I am close to release of my first game, and I really want to start beta testing, but I can’t work like this.
I am working with a decent amount of translucent water, and I have quite some tree instances in my level, however that was has never been a problem before and it never affected the speed at which I could edit my scene. I have several rivers that are made with the Ultimate Rivertool from VAE, and the editor started to act as slow as it’s doing when I was tinkering with the UV flow wrapping. I am currently using a directional light as my lighting, and I have a fair amount of instances of the wet_rocks_BP in that pack in the scene. Also I have had these assets in the scene for a long time a have never had any problems with them before. I am just stating this to inform you about things I think might be affecting this problem.
I hope anyone knows what this problem might be. I have already looked at different posts on the forum about the Lightmass crashes, but everything I have looked at and tried didn’t work. I am asking here because I have run out of options really. Can anyone help?
Kind regards,
Thaniels
