the top video is what i have and the next vidoe is what im trying to make as well as the screenshot I have but im not sure what im doing wrong
So the exact problem is that you don’t see your preview in first person right?
From this point on I’ll start to guess as I’m lacking the info needed.
I’m guessing you are trying to build a MP game and you are able do it on your server but not on your client.
The reason this might be happening (I have no idea if it is) is because the client cant just call SpawnActor. The spawning is only ever happening on the server so you need an RPC in order to spawn anything. Keep that in mind later on when you actually construct the building.
For the Building Preview though you don’t need to spawn anything. The way you do it is to attach a green mesh on the character/first person camera and switch it when you change the building, and hide it when not building - cheap and easy.
Now if you try to build you have to send an RPC with the position and the type of building you want to create and let the server handle the rest.

…that is if I correctly assume what’s going on. Otherwise, don’t mind me 
I do not fully understand I’m on a server and it working but jus goes to my head alot.
