Post-Process Anim Instances do not have BeginPlay called. The proposed fix is to add
Open the third person template project. Delete the character from the level.
Within the third person ABP, on the BeginPlay event, print a string to screen.
Set the mannequin's post processing ABP to the third person ABP.
Place the mannequin in the level and play.
Notice: The ABP's BeginPlay is not called and no message is displayed.
Expected: The ABP's BeginPlay is called and a message is displayed.
