Lakeside Cabin Environment (Unreal Engine 5)

I am currently in the midst of two projects (One in UE5 and One in Unity) and both have run into various errors I'm trying to fix or seek help with. Instead of twiddling my thumbs, I decided to work on a small environment scene as I love creating levels and worlds. The concept was simple, a lakeside cabin in an idyllic forest. I set this up as a blank project and created a landscape and sculpted the area i wanted to use. I brought in a modular cabin asset and then ensured the textures were applied correctly. I then added the water plugin and added a lake to the scene. At this stage the project looked like this: Not a bad start, I then began to add some assets to the scene, starting off with rocks along the shoreline and then adding foliage making sure to enable wind. I also upped the vibrancy of the grass and flowers to give a more ethereal look to them, the vision changed slightly from a duller environment to something more serene. By this point things were looking much bet...
