Actors/Objects visible inside editor preview window, but not visible in Play mode
So I have a level with a bunch of actors that were animated in Maya, exported as FBX, and imported into Unreal. I am controlling their animations via Matinee. All of the objects work except for two, which render fine and are visible in the editor preview window (and when running the Matinee) but when I enter Play mode, it doesn't seem that they are rendering at all. The weirder part is that sometimes they will render and I will be able to see them just fine, but this is rare. I've reimported a dozen times, and the settings are all the exact same as all the other objects. I've tried changing materials as well but to no avail. I've also tried increasing the bounds scale, have verified that 'Visible' is checked and that 'Actor Hidden in Game' is not checked. I am desperate at this point, as I have only until Sept. 24th to get this working, and I can't seem to find anyone with the same problem. Help would be greatly, greatly appreciated. Thank you.

I downloaded your project and then followed these steps.
Under animation where you have Use Animation Asset chose as Animation Mode. Under that there is a tab for Anim to Play. You have none assigned. I assigned the respective laser beam animation and when pressing Play in Editor I saw the laser beams appear. After that I switched them back to none and saw them disappear. I then assigned them again and they were playing again.
I believe you have the laser beam animations assigned to play in the Matinee but not in the viewport.
Let me know if this fixes things.

It could be the shear size that is causing this issue. UE4 by design is not a space simulator. We try to discourage extreme values for certain things. For instance, if you had a very far off distance, and you had a zoom function that allowed you to zoom in on it from say 3000km away, and you zoomed in on an object. If that object was close to another, or overlapping you would see artifacts occur due to UE4 trying to calculate what takes priority on screen.
The other factor is how fast you are moving. I didn't see the "objects not showing up," as you described. However, when flying around two planes, i'm assuming earth and moon, were stuck dead center of my viewport.
I would look into this and see if you can adapt your project.
For examples you can go to the UE4 launcher and grab the content examples files from the Learn tab. In it is a map labeled "level streaming."
I really hope this helps and good luck with the deadline.

I had a problem like this but with Sequencer and with characters in a hallway type room. I found this solution worked fine to solve my disappearing characters but I had some anim trails through animation notifys on the animations the characters were performing which never came back. I guess that's not too bad overall really. The level the characters were in was of a modest size rather than a big space scene so I thought it might have been to do with running out of video memory or something like that ?
