I got an idea..... Ther are a couple of programs out there called MagicFPS and Signs III... Both are excellent for putting together what your looking for.... And there is a nifty program out there called photoshop or its competitor paintshop.... heck if your good you can even use MS Paint..
Just a thought try reading the stickys.....
Oh yeah they released model pack 3 that has windows and walls etc may wanna look into that also...
Hmmm and last suggestion before I am out of this thread try using the search feature below before making a request you may find what your looking for has already been posted...
Have you downloaded your CLiPs today.
