I recently created a throwing hammer for a Neverwinter Nights 2 persistent world, Engines of Ascension. This unfortunately took me well away from the wonderful world of PBR, as NWN2 only supports diffuse, normal, and greyscale specular maps, but it did afford me the opportunity to use a normal map to beef up an extremely low poly model, though not necessarily by the standards of 2006.
This project has also opened my eyes to where I need to focus on developing my skills. There is some waviness to the normal map which I need to work on in the future, which resulted from lack of supporting edges on the low poly model during the normal bake. There are also some problems on the hemispherical hammerheads, particularly on the corners of the hexagonal back.
