A genuine steampunk hat, complete with a skeleton key to everything.

Texture Set #1 - 2048x2048
Texture Set #2 (Glass) - 256x256 (not used from LOD2 onwards)

Terry and Human:
LOD0 - 6,763
LOD1 - 3,489
LOD2 - 1,700 
LOD3 - 699
LOD4 - 110 

The model was created in Blender. It was modeled directly as Low Poly and used as LOD0, so no High Poly version was made.

LOD0 - Full original geometry.

LOD1 - Small details and geometry hidden behind other parts (not visible from a distance) were removed, followed by polygon reduction.

LOD2 - Medium-sized parts were removed, along with all glass elements. Glass material usage was disabled, followed by polygon reduction.

LOD3 - Only the largest main parts were kept, followed by further polygon reduction.

LOD4 - Only the hat frame remains, followed by final polygon reduction.

Polygon reduction was performed using Polygon Cruncher, which delivers excellent topology quality (see screenshot below).

Texturing was done in Substance Painter.

Screenshots and videos were rendered in the Substance Painter, s&box editor and s&box.
