Problems with Creating an Object

[s0Srs]

Hey,

So me and a friend re-opened our Server and we didn't want to remap everything and it also has its limitations. We decided to make models so we could have way more detail. I imported a model in 3ds max with KAMS script, changed it a bit and I got it to work ingame. Since I'm new to this sort of stuff I don't know how to make the textures in 3ds max and the collisions for an object. I tried by some tutorials but none helped. Here's a screen of the building (It is the vgnfirestat just remodelled so it has interior) If someone knows how to correctly make an object with textures and collisions I would appreciate your help.
