Invisible assets in play mode, seen in viewport. Texture pool?

Hello

I am currently working on a video game level for a project and I seem to be running into several problems. The first problem is that when I am working on my level I can see foliage and other assets in my viewport as shown below

When I enter the play testing mode however, it appears that all my assets have disappeared

I am very very desperate to find a solution to this problem. I have tried to find an answer to my texture pool and how to increase it so that Unreal Engine will be able to run more smoothly. If anyone has any suggestions or solutions please let me know.

Thank you so much for your time

Make sure you don’t have “hide in game” checked in the details panel of your assets. That would be my first thought.
