The mesh is finished but I am not sure it would behave in Unity.
As a force of habit I ran a limited dissolve as soon as I was finished, I do this with the props I make since many of them wind up being very complex (e.g beveled, chamfer swords with ricasso and fuller. This extra geometry requires that I remove as many verts as possible so that it can easily be uploaded into the low mem games I make them for. that being said I was not able to use the decimate tool to any avail. I hope there is no hidden difference between the way they remove geometry.
Ehm, sorry for the book guys.
