Well to keep our stuff separate we have a folder set up and keep all of the sample stuff under the root directory and each time a new sample comes out we migrate the assets to be used as part of the frame work. This gives us the opportunity to see if there is something that we can use and if it fits we make a copy to our build folder.
So no there are no pitfalls as it’s just raw data.
It works really well as in when you migrate you also get all of the blueprints and game types and our environment artist can easily switch from one game type template to another with out having to start from scratch using a quick start template.
Need to switch from 1st person to 3rd person click on World Settings and set the GameMode override to a game type that uses the template you want.
Want to give it a test drive migrate Mixamo sample to the shooter sample and switch to override to the MixamoGame.
