Hi, it’s a specific question regarding the G-fur plugin in ue 4.27.
I downloaded the plugin here: gFur 4.27 - GiM
I followed their tutorial to install (make a “Plugins” folder in the project folder, unzip the plugin inside it and finally enable it in ue4)
So basically when I try to package my game, the error that you see in the title occur and I can’t find a solution online, I need to use this plugin but this problem just make my packaging fail. I guess “definition” means something should be written in a “definition” block of code or something like that?
If someone has a solution I would love to hear it 
Thanks in advance!
