[TEC] Some questions about submarine 3D models

[Hitman]

Having learned a good deal of modeling in the last years, I was wondering about the specifics of SH4 submarine models, in case I had some time to crank out one. Can someone help with these questions?

1- What is the desirable amount of polygons for the hull and for the conning tower? (I know guns, rudder, periscopes etc are separate objects as well as the conning tower)
2.- How many textures can a model have linked to, and what is the proper size for them?
3.- Do textures accept alpha channels f.e. for railing or holes?
4.- If I provide a model in 3Ds or Ligthtwave format complete with textures, would anyone be able to port it into SH4 adding the animations for torpedo doors, peris, rudder, screws, etc?

Now I'm not saying I will start modeling something tomorrow, but I want to know how the models should be, so I can gauge the work needed and see if I find the time for it.
