Walking through walls and coming through the other end

[Queenss_RA]

Hi Everyone,

I am working in a CAVE, where I am building a environment with 1000's of cubes just randomly placed in a 100x100x100 area.

I am navigating through this environment and wanted to know how I could make it feel like a infinite universe without the need of drawing all these objects over and over again. I have thought of making it by saying once you leave from one side of this world you automatically enter from the other end, however, I do not know how to implement this. Any ideas?

Thanks!
