Problems with collision

I finally got a scene done using dae file. I setup collision on my models but when uploaded to web there is no collision. I added after final bake. Does collision need to be baked? Only the walls and doors take collision.

The collision is not related to the baking process. Could you send me a link to your scene so I will take a look?
You can send it to me via private message on forum if the scene is not public yet.

I found out why by looking at other posts. I guess collision only works for things at eye level which is why no couches or anything have collision.

Yes, collisions work for the camera, and the camera is just a point in 3D space. So, if you lower your camera and walk into the sofa, then it will work. You can set up some invisible geometry around the furniture if you need.
