[4.8.1] Crash on lighting build

Hi minhgnob -

Typically with an engine crash you will see the Crash Reporter (pictured above) and even if you didn’t there would be a report directory created. Try opening Windows Event Viewer and look for Critical or Error messages that occurred at the time of the crash (give or take a minute) and save that information out to post here.

It sounds like there maybe something else on your computer which is incorrectly functioning with the engine.

I would run a Windows Update and Video Driver Update to ensure that I am on the latest versions of my system files and see if you still get the same error.

Finally take a look at your DXDIAG, you will want to have more than 4GB of RAM and a Quad Core Processor at least to successfully build lighting.

Thank You
