Hmm, interesting I've used blender and the like before. So that might be an option.
Out of curiosity what should I look for exactly in terms of the tutorials if you were to narrow it down?
I would prefer in-game as I've fiddled with 3d stuff before and it's very tedious. The biggest thing I'm most curious about are the random walking or fighting scene
You're welcome, I believe some people also make the machinimas directly in 3D modelling/animation programs, but some of the ones I have seen around use the game engine directly.
