Hello, Did anyone manage to find a solution to the problem? Error: Failed to build augmented image database. I work on the binary version of UE 4.20
EDIT :
I have done that but when I start my project I have this error message : Failed to load Plugin : Failed to read file. Invalid Json Token. Line: 7 Ch: 1 (E:/Myproject/Plugins/GoogleArCoreServices/GoogleARCoreServices.uplugin)
