Hi (?)
Well…I have a lot of time with the obsession for make my own projects in Arma 2, infantry,aircraft,vehicles… i have lot of ideas, but i am a super Noob in that. I want a Sensei for teach me or maybe a super tutorial of ‘‘Do it yourself’’, maybe i can live with that.
This is a forum for blender’s integrated game engine (at the top, you change the rendering engine to ‘Blender Game’). As a result, we know nothing about Arma2. I suggest you go to the Arma2 forums and ask there.
That said, in general, modling for a game is not much different for modelling for render, except that you have to export it to some game-readable format at the end. What that format is for the ARMA2 engine, I do not know.
