First change: bGenerateOverlapEvents from UPrimitiveComponent changed from “bGenerateOverlapEvents = bool;” to “SetGenerateOverlapEvents(bool);”
Second chage: **bUseControllerViewRotation **from CameraComponent got_DEPRECATED.
Now you have to use bUsePawnControlRotation.

The point is: IntelliSense tells me that bUseControllerViewRotation is inaccessible, but on 4.19 that was not happening.

Third chage: I’m getting errors with a function called on my Slate Widget Tick() when playing, after a few seconds
pt-BR to en-US … [787] LogWindows: Warning: CreateProc failed: The sistem can not find the especified file. (0x00000002)
CrashReport:
My code:
As you can see, “Create”, “SetScalarParameterValue” and “SetTextureParameterValue” are inacessible (IntelliSense).
Changed the #include lines (and paths) to header file and the result was the same.
