Live and Reloaded was a “direct port” of the original N64 game to the Xbox, along with huge graphical updates. The image in the OP is Conker from the N64 version ported in to Gmod. He wants Conker from the remake, which looks like this:
Unless someone codes a fur shader in to Source, it will look pretty terrible. You could probably remove the “fur layers” but then he would look really matte and bland, but I think that’s the best you can do. It would certainly be a step up from the N64 port.
To be honest I’d love to see some ports from this game as well, but that requires someone with the know how, and I’m not certain if it’s possible to port from this game to begin with.
