Beckstation, you are right the high poly meshes are fine for animation but only if you do not plan to have them move and they are being uses as backgrounds... Generally speaking the high poly meshes especially the ones with mixed triangles or odd faces cause all kinds of issues. Right now I have been working with 3D printing a lot and the high poly meshes are horrible. They mess up my prints or make the printing process so much slower. The biggest issue is some people don't build their models from scratch anymore making sure that the grid is done properly. It is sad because then whenever I buy model like that I end up having to ask for a refund and can't print it which wastes plastic and time.
