I got an email to say responded, but I can’t see his response here.
He says:
"Hey Otreum-
When you make the copy of the project in 4.9 does it open in the editor properly or does it fail to open as well as compile? What are the Visual Studio errors when the 4.9 version fails to compile? If possible, could you send me a copy of the 4.8 project that I can upgrade to 4.9 to test myself? To do this privately you can upload the project to dropbox and then send me a private message on the forums with a link to download the project.
Cheers
"
To answer Dougs question, the project can open perfectly ok inside of the editor, I can run around, and play/test it like normal.
The project is 100% blueprints, I don’t do any C++ work (yet), so as far as Visual Studio errors go, I really couldn’t say.
I did a bunch of trouble-shooting since posting this query on AnswerHub, and eventually looked at the big glaring error that says:
[2015.09.09-00.51.19:506][ 0]LogInitisplay: LogProperty:Error: UStructProperty::Serialize Loading: Property ‘StructProperty /Game/MyContent/Blueprints/Vehicles/PowerLoaderAnimBP.PowerLoaderAnimBP_C:AnimGraphNode_ModifyBone_2B24B5804DB962B0535FBCB59EA39E5A’. Unknown structure.
This is within a vehicle blueprint animation, I had to delete a Transform (modify) bone node and compiled with success, which was really bizarre since it works in 4.8.
I feel kind of embarrassed that I didn’t look at that sooner, I thought I already tried it and it failed, but I guess I didn’t. (Honestly, when I looked at the error log, I didn’t know where to start).
Is there a way to get the error log to show more than just the first 50 errors?
I checked at the actual log files themselves, but they just show what the Output log shows.
Thanks for taking the time to respond, and doing so, in such a quick time, hopefully the project file I sent you will have something that can help epic games in making the engine more bug free.
Cheers!
