I get a strange problem with version 4.17.1
I don’t know why but after have update my project some blueprint is very very slow to compile.
Exemple my character blueprint taking around 3 or 4 secs before and now with 4.17.1 it take around 1 min or more… and the computer seen to work very hard on the compiling comparate to before.
I have many AI character too they is pretty much all the same BP code, the only difference some AI use a different controller and bone hierarchy. It’s strange because some AI Character BP compiling fast and some other compiling very slow. I have try to search and find any difference with the fast and slow BP compiling and I see nothing that can cause this slowdown.
It is possible to see a debug in runtime of what happening when the blueprint compiling ? maybe it can help me to find what is the cause of that slowdown.
I am also having the same issue with 4.17.1. I tried on a new empty level, and the main character compiled far better. But after a few changes, in the same empty level, the compiling time is the same as in the previous level.
Ok, It seems that if you disable the Compilation Manager in the Project Settings compiling time becomes like It was before! I mean, it goes from 12 seconds down to 600ms after disabling it.
I had the same issue, after moving form 4.16 → 4.17 the compilation time went from 3 sec to 60+ sec !!! sometimes 2 minutes.
After disabling the compilation manager the compilation times were fast again as they were in 4.16
There must be something terribly wrong with the compilation manager.
