i've spent hours today making this for a source map. i only have a couple of photos i took at longues sur mer battery last summer as a reference, and i might add some more detail after i found another photo on my hard-drive, but that shouldn't take long.

anyway, i've unwrapped it all, the outside case thing is a 1024x1024 jpg, the gun itself is 2048, but could just be resized to 1024 if it has to be. i could try and skin it myself, but i can't even get a decent base metal texture and it'd take me weeks to finish it. i can send the model in any format max7 supports if anyone wants to try and skin it.

To be honest, you could probably get the whole thing in one 1024 texture. Its not going to have that much detail, especailly on things like the barrel so you could make things a little more economical that way.

what is the link for the MDL and the map

here's a link i posted at some other forums, which includes the model in .3ds, .max (max7, if that makes any difference), the 2 uvmaps and what i had so far on the outside shell.
i can upload any other formats if i have to, besides .3ds and .max
