I am confused at exactly why the LOD doesn't work as I expect it to. After reading the docs I have gathered that the window resolution, FOV, and camera position to a Multimesh AABB point are what the engine uses as criteria for determining when to decimate a mesh. I have a large piece of terrain in which I had initially placed a single MMI, but it was having some issues once I got towards the center of the terrain as the camera at that point was too far from and given point of the AABB. I decided to make 4 quad MMIs to counter this issue but am still not getting results I like. I have tried adjusting the basis and also the threshold.

Here is a photo of the render in which one of the MMIs is being decimated although it's still in the camera view and the camera is near a corner. I understand the docs as the closest point of the AABB will be used as the basis.

If I turn the camera slightly then the meshs look fine

I can't find anywhere that states the which direction the camera is facing will affect the render but that seems to be the case as I've had the camera in multiple positions and just the rotation left or right cause meshes to decimate.

Here's an overview
