   Level Design software
  Does anyone know of any good free level design software? I know model software can create the architecture but stuff like Anim8or seems as though it was just create for models and not complex levels.I guess i'm asking for modelling software designed to create the architecture of a level. Anyone know any good stuff?   
  I'm don't know how modifiable Valve's Hammer Editor is, but from what I remember when I used it a few years ago, it is very nice to build worlds in.   ;  hmm, i read somewhere the things used for it could only be used with half life and source. is this true?   ;  try getic easy editor to use but to bsp file is quite annoying to load, but it can be done   ;  Cool. It seems nice but the bsp thing is turning me off, that method seems so ancient.Anyone know of any portal based level editors or that like Unreal tournaments style (cutting the level into a block)?
