ue4 crashed after gpu lightmass calculation done.

If you’re trying to do GPU lightmass it may have run out of video memory.

yes i am using gpu lightmass, i have tried two times but every time it crashes after build completes. i have gtx 1060 card 6gb video memory,how to run lightmass build without running editor, would that help significantly?
