Something is wrong here regarding this. I have 24GB RAM and NVidia 1060 6GB, worked in a lot of UE4 projects before and never ever had this problem… until just now.
I’ve purchased an UE4 marketplace product so I wanted to test it. I have made new Architectural Viz default UE4 2.24 project and added new content to it.
I was able to open showcase map, everything was looking good and shaders were compiling… and at like 90% done I’ve got this message.
Started project again, this time I tried to open just a level with meshes, it opened ok but I’ve also got this error at like 90% shaders compiled.
Next time I have opened project I was not able to load any of those 2 maps as I am getting “out of memory” errors asap.
I don’t think I am actually getting out of memory (both graphic and windows) at all, something feels really bugged to me.
I have tried some solutions like increasing swap file size but nothing helped. I even made second swap file on my system disk hoping to mirracle… but nothing.
I have deleted downloaded stuff from the “content” folder and downloaded it again, but I am getting message asap now so it feels it is now “saved” somewhere.
It feels wierd that i now can’t open those maps at all.
[EDIT]
Same happened in 2.23, but I’ve managed to open the level with only meshes first.
Memory in UE4 was around 2.2GB, and graphic memory was constant 1.3GB without any spikes in memory history.
