I am working on a zoo tycoon 2 like game to get A better understanding of unreal. I currently have the main menu and zoo selection parts done, you can change some settings, and enter an Demo Zoo level. I also added the 3 main player characters, the bird eye view mode to build and change stuff in game, the zoo keepers mode and the camera mode. Now I want to be able to add the object placement for the build mode, but I can’t find any info about it exapt from an UE4 tutorial of a city builder game, but half of what he used has been depricated and removed. Can someone help me with this?
Hey @ReinierTheGhost!
You can check out these tutorials:
to get an idea of how the essential part should look like and implement it to fit your top down scenario. You can also check out the following tutorials of the same series but I think after figuring things out you can implement those extra features better on your own to not go too far off your use case.
Hope this helps! 
Wanned to add this as well, dropped just a few hours ago:
