Hello everyone, i have a strange question. When the num of cpp file less than 28 , it compile success, and i create one cpp file and the num greater than this number, it compile fail. If i del this or other cpp file, it compile success again. I think it is really really strange, because i didn’t change any other things, just create one cpp file by UE4 Editor, success will turn to fail. Could anybody help me? Thanks !

Sorry,here is the Output , I think UObjectGlobals.h is the Engine file , I don’t know why it is error, but if i del one my file it compile succeeded again
Oh,It’s my error, I should use ObjectFinder instead of LoadObject in a Construct Function, Thank you very much !
