What kind of texture technic is he using?

Hey folks,
recently I watched this level design by Maverick. At minute 0:30, 0:40 he is composing multiple wallparts. The texture seems not to be mapped on the model itself, instead it seems to have a global setup or something. When he moves the models the texture stays on its place.

Does this technic exist in Unity and how is it called?

Thanks in advance!

 

It's a technique where the texture in the shader are mapped in worldspace using triplanar projection.

 

That makes sense, thank you!
