I can model any thing but I struggle to texture a cube. Substance Live is correcting that but them cubes ,gezz ;)

Poser threw in SubD's in 2014.Hence why V4 has a ridicules high poly count. So make your 3D dodecagon edges high polycount like ya did with ya #5. I'd render your mesh with SubD's activated.

All the .jpgs you posted ,no UVMap.Your odd artifacts around the edges are they where the UVMap seems are ?

Could it matter how you make your maps depending on what App , lights and render engine you use ?

I wouldn't turn bumps on very high.

In case you start missing with Normals Tangents are important for Normal maps.
