‘source other than the UE4 marketplace’? what? I bought Military Pack from martket place and the thing is that many stuff, not only from this package, is not production ready. Still, even on 4.7 I can not autogenerate UVs on truck from the package I have mentioned on the begining, I got crashes everytime. Actually I’ve already mailed to the epic staff about all those ‘production ready’ content from marketplace. The only answer I got was that they can give me a refund. So instead of getting high quality content or at least working with the engine we get ‘whatever’.
