Hi Osama
If I understand you right you want to export an insrance from Max and want Unity to se it as instances too just like in Max?
The instances link get nuked at export.
Solution:
Export all your instances as one “FBX A”.
Place “FBX A” in the scene.
Export a clone of one the instances as your main object “FBX B”. (I prefer this objects position to be 0,0,0)
Use your main object to create a prefab “Prefab B”.
Copy this “Prefab B” and replace all your objects in “FBX A” with this “Prefab B”.
Then delete your “FBX A” from your scene.
Now you got prefabs in Unity instead.
Hope it helped… 
i understand u ,
that is mean there is some limitation in the Exporting process ? , am already do this process with Virtools engine without any problem .
copy instances in unity as Prefab nice idea , but i have about 60 object in 3ds max file as instance , that will be hard if i do the replace for each model .
See the model in the attachment .
60 hehe that will take about 6 minutes
AND your download size will decrease as you reuse one object.
i will try and update the topic 
Thanks for u :roll:
