Just in case it wasn't obvious - Blueprint Compilation Manager is STILL broken in 4.19...

So, in 4.18 it was pretty bad and we could disable it. In 4.19, you added this neat feature which keeps BPs dirty after disabling the Compilation Manager…

A feature no one asked for. Supposedly in another thread, a dev said the toggle is going away… that’s* cool*.

So this is a relatively average sized Blueprint in 4.19:

Compilation Manager Off:

Compile Time = 8k ms (8secs) (but BP remains Dirty)

With the Compilation Manager on… same BP:

over **1 minute, my gyazo ran outta time…


**

Here is the final outcome:

83k ms (83 secs, 1min 23 seconds)

Conclusion: Your Compilation Manager is broken. Please fix it in a hotfix (so it doesn’t remain dirty) in 4.19.x, until it works as it’s supposed to.

Same here, stupidly long compile times. Forced to use compilation manager as the ‘dirty’ issue is in the “won’t fix” basket (Unreal Engine Issues and Bug Tracker (UE-56457)). Why fix something that isn’t broken, or better yet - why try “fix” something and make it even worse then push it live?

I routinely have to wait 5-10min for a single high use blueprint to compile… and yet on most occasions it is quick… like 2-5 seconds.

Very irritating. I also can’t turn off BCM because everything remains dirty now… reduced my productivity enormously!
