Can't let go of the sprite on the layer below, which are not visible 3d objects in the scene, turned out to fix with the new object and mesh renderer, but the sprite loses quality and becomes not responsive.
MB can we fix it ?
The parameters canvas'and it is possible to increase Plane Distance. This will stretch the background from the camera, just need to change Render Mode to Screen Space - Camera. Or Vice versa zoom in on 3d objects.
