Can we take a look at your master foliage material? I’m curious there might be something in the opacity channel that’s driven by object position or local space. The instanceFoliageActor (responsible for rendering foliage) is one object. Sometimes that ends up breaking some material operations based on object position. If your foliage is part of an asset pack, one thing you could do to test is to select the working foliage in the world and drag it around. If it disappears past the same point relative to the landscape, then this is exactly the issue.
