LogInit: Display: LogOutputDevice: Error: Ensure condition failed: false [File:E:\UnrealEngine\Engine\Source\Runtime\Engine\Private\StaticMesh.cpp] [Line: 3901]

LogInit: Display: LogOutputDevice: Error: Accessing property HiResSourceModel of the StaticMesh while it is still being built asynchronously is only supported on the game-thread. To avoid any race-condition, consider finishing the compilation before pushing tasks to other threads or making higher-level game-thread code async aware so it schedules the task only when the static mesh’s compilation is finished. If this is a blocker, you can disable async static mesh from the editor experimental settings.

Hello,

The line numbers for a couple of functions in the stack do not match the engine code. Did you customize the code in StaticMeshBuilder.cpp or StaticMesh.cpp?

Regards

Yes, how to check the race-condition?

We have some classes that can help hunt race problems. You can look at the MTAccessDetector code. The end of the header declares a couple of header macros to simplify the usage. You should be able to find usage examples through the engine sources.
