Cannot understand if I'm doing right with textures

[GTU]

Box mapping was the keyword
I’ve found this

Apply 1m x 1m x 1m tiled box UV to all meshes

I found the following example: [image] Multiple types of procedural unwrapping, found in most 3D software, would be nice in Three js. The box unwrap would tile the UV space from 6 axis directions for Xpos, Xneg, Ypos, Yneg, Zpos, Zneg

So my practical problem was solved, thank you.
I still have to better understand how it all works.
