Multiplying mesh multiple times in Blender I'm trying to create a mesh in the shape of acoustic foam. This foam is used to cancel out echoes and is also used in transportation:



To create such a material, I add a cube, then I select the upper 4 vertices and click Alt + m, then "At center".

This creates a pyramid.

How could I now multiply this pyramid in order to form such a foam object?

Thank you!
To create a "matrix" of objects, just use the Array modifier twice with the Relative Offset set to x=0 y=1 z=0 and x=1 y=0 z=0 as shown in the screenshot:
