Very nice. I'd be interested in learning how you "templated" or otherwise fit the boot to a foot shape within Carrara. I haven't found a method I like yet; I'm still building blind and resizing after export (which is why my models are still very simple). Good to know what the .obj problem was. I had a similar issue on two models that cleared up only when I exported as DXF and re-imported. Now I understand why that worked.
