Modeling weapon questions

I was wondering how people make guns look so realistic in gmod when they can only make simple shapes with a modeling program. Please help me out, thanks.

What makes you think they can only make simple shapes with a modeling program?

Oh well all videos i see only show them making hexagons square and cubes, that kind of stuff

Uhh what. You need to get to know all the tools on your program, tutorials are a good way of getting hang of them. Don’t do gun tutorials, start with general ones because it’s not the results but the technique you should be going after at this point.

What program are you using anyway?
