Should i use multiple ID for my mesh?

Hello all.
I just finished my model (it's for Unity), It will be a metal  on structures (bottom of the modele) and  cloths  on the top of the modele as you can imagine logically..
But i'm wondering if i must separate metal/cloth uv

other doing on multiple textures :

So what should I do with my operation chair? 

Thanks a lot

It really depends on your texture budget and level of detail you want to acheive. If you don't have real time performance limitations, you'll be better off separating it in a few texture sets/UVs for a better texture resolution and easier work in Painter.

Thanks for your answer Jerc

It's for  a game in Unity that mean yes it will be real time performance limitations like any game, it's not for a movie like Adam (Tech Demo in Unity ) But a game AA indie  with great graphics or AAA like last of us 2013 environments then should i go with 1 or 2 texture set?

Thanks
