Hello, I am new here, my name Is Jordy Smeets I make 3d models for train simulator 2001 I use G max, and have paint net and paint shop pro

I made a 3d model for an old game of mine (Train Simulator) Though I am not good at textures.
My textures don't look like metal, and when I try to make it look metallic it ends up grainy
I want to be able to make realistic looking trains (Mainly in textures, the game I work with can't handle to high poly counts.)
People who know Half life 2 (or other games with good textures) probably know what I want.
I searched for tutorials on this topic but found nothing usefull, (Mainly brushed (Not 3d model use able) texture tutorials)

There are some very good metal making tutorials I can link you but my post count is not 15! haha

Yes, there is many tutorials. For example this http://www.3dtotal.com/ffa/tutorials/max/metal_surfaces/lotsmetal.asp

Your texture looks better then my textures...
