I've searched the forums, and was unable to find an answer for this... So if you know of one, bear with me here...
I've noticed several maps that are basically classic maps, but some aspects of the architecture and layout are changed. So my question is... How is this done? Is there some way to open an existing .bsp in Hammer? Or is there some other program that converts it back to a workable .rmf? Any insight on the matter would be helpful.
It might also be helpful if I could get instruction on how to convert a .bsp from one HL mod to another (i.e., Day of Defeat to CounterStrike; Half-Life to The Specialists, etc.)
