I think the only way you could make Enki fur is to bump map them. Adding real time fur would destroy the game. I don't know who the modellers are, but as far as I know, to bump map you could just port the original models into blender and use the sculpting tool to add the details. I forget how it works from there, but I've done a bit of 3D modelling, also been watching the overgrowth development blog and there's something about it on there, although admittedly they're using Mudbox to sculpt rather than blender. Still, with the new Crystal space engine update, if it's enabled, then this would be the way to add Enki fur.
