Are you going to work on walking through the portals?

I use 20 RenderTextures, but I update them in turn with a certain pause, but this system requires a lot of resources, but I use ForwardShading and
I do not use dynamic lighting, so I do not use big scenes, I use small rooms with transitions between them. (
stable 95 fps) portals will be functional, they can be interacted as in the game “Portal” (sorry for my english)
