Problem with Reflections in Three js React


I have a Problem. I cannot realize reflections for some objects in three js. The result that I obtain is a too big image for the reflection. I explain.
What I do is simply create a background for the scene using six images:

then simply for every object i have i create a cube Camera that takes pictures of the environment and projects them on the surface:

Unfortunately the result that I obtain is this:


It seems like the reflection is too big and just a little part of this is projected.

Any Idea?

I am almost desperate…
