Making collision for Architecture (Interior)

[Ravejob]

Hi! im a new modder that recently decided to make use of his 3D modelling, Sound design, animations and texture skills. Only problem i`ve encountered is the lack of information on how to make things such as custom collision (for interior spaces). Also i have noticed people mentioning 3DS max 2013 specifically for collision. Anyway if anyone can drop by any helpful tips or links to helpful guides i would appreciate it.
