Preload plane on route change

Hi, this is a test:

https://next-boilerplate-9z8u5vj8x.vercel.app/orto

when change route from orto to orto1 and viceversa there is a blink of plane.

onroutechange load the plane of a specific page.

How resolve the blink screen?

I would like to load the textures of the single mesh and then replace the scene avoiding the flashing of the single planes
