Hello , this is my first experience to make a game, can someone direct me please and give me a clear explanation on this. ?


I just want to make a 3D cube world and in it small cubes that fill the larger cube, and it will be only lines between them not closed walls, and I want to make each small cube as a hollow object where a player can start with. 

please I need this, would much appreciate it if you help me with this.

Thanks.

You make the boxes visually -- filled or hollow -- by creating art assets for them.

I imagine both could use a cube model but the hollow ones could use a texture that is transparent everywhere except the cube's edges. A more complex form could use a different model that defines each of the edges as a smaller shape.
