My first plan was a crate this is an amazing filler type item, although not amazingly detailed it’s a perfect filler to fill in empty spaces without overly detailing it to keep some negative space to make the room not feel so cluttered.
Poly Count: 912
Making this was relatively easily, just a cube with extruded edges and extruded faces that were rotated to be diagonal.
In my environment I used them to fill up the corner of the room to fill up the empty space.
