Answer is in front of you

FMemoryWriter does not support data larger than 2GB. Archive name: //Game//StarterContent//Maps//Appatment_T5

Something is too big

As you can see i deleted all the different unmap. kept the last one, but still same problem…

Hi masteroner,

Can you post a copy of your dxdiag here so I can take a look?
