I seem to encounter the same issue, yet I don’t have large nanite meshes.
The largest memory it’s trying to allocate is “UATHelper: Packaging (Windows): LogAsyncCompilation: Display: BEWARE: AssetCompile memory estimate is greater than available, but we’re running it [StaticMesh] anyway! RequiredMemory = 0.000 MiB + 1236.7771 MiB, MemoryLimit = 553.222656 MiB”
Been at this compile issue for over a week now, have you been able to find any solution to this?
