Seems like it.
I think the surface must be directly proportional to the distance from the camera, so as the camera moves further away the reflection surface has to be bigger and viceversa.
I’m totally “guessing” here as I’m not sure if this is the only and right way to solve this problem but from the tests I’ve done it seems it works like this.
If there’s a better solution I’m up to hear it since in this specific case I can solve the problem by increasing the size of the mesh but in another project I might not be able/cannot to do it.
