In my experience with UE4… I have never had a crash while compiling:::EVER, BUT, I do have had errors causing the compile to stop even in an early stage (during packaging), sometimes plugin related, that’s why I don’t like to use marketplace plugins… somehow most of them work great in the engine, but I don’t think developers are making packaging test, If UE5 is crashing during packaging or compiling, there is no way, any external asset or plugin could be causing this, because marketplace developers are not allowed to update their assets for UE5 yet,
Maybe it is related to material changes in the engine, Nanite, Lumen, Chaos or a beta plugin,
My biggest concern is actually FPS, even if UE5 is released next month, if the default map starts with 40 to 60FPS… I won’t use it, because UE5 is between 30 to 40FPS right now in my gamer PC, while UE4 is way over 200FPS with a default scene, and if the only solution is to turn off Lumen and Nanite… then there is no point on using UE5 just yet, but maybe you should try to disable those features and then compile, just to run that test, but the fact that two sided geometries can’t cast shadows, or getting terrible shadows now and no displacement, is like a big no… I’m actually appreciating UE4 more these days, it is a masterpiece, I really hope UE5 is as great as it should.
