Dear everyone:
I am so sorry to have so many question, because i have no idea..

Question 1
I always see some object like house in the map.
Should i build the map and house in a same "object" and export to PS?
OR
Just create a simple map for one object and export to PS, and create a house and export to PS and put the house in the map?
Question2
I follow the Simple Modeling School and make a simple weapon, i know how to export to PS and replace the other weapon, but can i set this weapon in some where on a map?
For example:
I make a map call testBox, and i want to put a weapon in textBox with the location 0,0,0 (x,y,z)
Is that possible to do it?
if yes, should i change to data in database?
Can i find any tutorial in this forum?
