For one thing, don't use the CoronaCameraMod, it's outdated. Use an actual CoronaCamera :) The CameraMod was there for when back in Corona 2, there wasn't a dedicated Corona Camera.

What is that dark square in the middle of the render? Is it a shadow of some plane with exotic material applied to it? It seems that firefiles appears only on that shadow, so first thing i would do, is to identify what causing it.

Are those tree shadows from a geometric trees, or from planes with opacity maps? Do you suspect what can cause those dark rectangles to appear? Maybe there is some non renderable helper objects in your scene? Did you try to render from camera with regular perspective to see if those issues appears in them too?

Also, maybe you're using enviroment image wrapped on cylinder or sphere?

Make sure that your background material is correctly set up. https://coronarenderer.freshdesk.com/support/solutions/articles/5000515605-how-to-create-background-material-in-corona-
