Getting a bluescreen crash on importing large .uasset files

Hi there!
I’ve been getting a hard windows crash / bluescreen whenever I try and import any static mesh over 100mb, saved as a uasset, from a specific pack.

I’ve checked the pack on a different system and it’s fine, so I’m assuming it’s something up with this computer, but I can’t work out what. I’ve had multiple error messages from Access Violations, QuadricMeshReduction & even just generic “Shader crash”.

I’ve tested my ram, HDD / SSDs, CPU speed and everything is fine & healthy. I can even load up the Electric Dreams project with no issues.

Apologies if this isn’t the right category too.

Additional info:

Meshes have confirmed to have less than 64 material slots
Combination of Nanite & non-Nanite meshes, both cause the crash

Current system specs:
Windows 11
Unreal Engine 5.3.2
64Gb Ram - 6000MHz
i9 13900KF cpu

Tested on both HDD & SSD, internal & external

The system that could open the project has similar but slightly lower specs across the board.

hi @ACEdwardsAudio
Blue screen is often a symptom of needing a larger pagefile.sys
see
Adding a larger pagefile.sys

Make sure you have a larger system files as well

Hey, not sure if this helps, but when I had a similar issue, I fixed it by cutting down the number of polygons in the imported asset. Give that a shot—simplify the mesh and toss it into UE. Another trick is to start a fresh project and see if that sorts things out. Oh, and keep an eye on GPU spikes in Windows too. Cheers!

Hi Jimbo,
Thanks for taking the time to check this out.
That’s a great idea, but unfortunately it didn’t stop the crashes for me.

It’s still throwing multiple different error codes too

Hey there!

Cheers for the ideas! Unfortunately I can’t access the models as they’re in uasset format & trying to open them in a project causes the crash :frowning: haha

GPU is all clear too, I was keeping tabs on the system performance & everything looks pretty normal.

Thanks for taking the time to have a look though!
