Mesh Distance Field on large scene

I’m having some pretty bad issues with DFAO. I’m working with a VERY big scene (skylight and directional both on movable) and I have those weird results:

While in the visualizer, meshes far away from the camera will disappear and those a bit closer will be like semi-opaque. There are also those weird patches that come and go depending on where I’m in the World. Some help or info would be super appreciated, thanks!
