Somes questions about Model Editing in 2.4.3

[doogle41]

Hi,
I just read some tutorials about Custom Models injecting and WMO Swapping-Adding and after After some tests Ive somes questions where I havent found any answers. Im working on 2.4.3 and with 3ds max 9.

- How to imports models from 3ds max into m2 with multiple textures? Ive tried in a lot of ways, not successfully, and the CryectsTools's M2Modder still tell me there's only one texture in my converted model.
- How to make these models collidable? The only one thing ive found is a 3dstom2 converter for 3.x wich do it, but not for 2.4.3
- Is it possible to change the models of the WMO? I mean btw adding WMO with models of mine.

Thank you for your answers
(And sorry about my english, dont hesitate to correct me)
