Hi Arthur,

Do you have any additional details, repro steps aside from just importing a mesh?

Is this only happening with a specific mesh or any that you use with 4.11? If it’s a specific mesh can you share that asset here?

Can you also post your DxDiag, specifically I’m curious how much RAM your cpu has since this indicates it was a crash with 12mb of memory that it was allocating.

Also please include the log that was from the project with this crash (Project folder/Saved/Logs).

Thank you!

Tim
