how can i make a House for FPS game in blender. I want to a house in which player can move inside it, i.e. move from onr room to other, move upstart, etc..
Pay a friendly modeller many 'quatloos' to do it for you, or alternatively learn how to model in blender.... it's really a question for the blender forum, after you've watched/read the many blender tutorials...
You can also have a look at wings 3d, very nice free modelling software easy to learn and start modelling. Eventually you'll want acces to the more advanced features of blender.
I'd agree, except I have a principled objection to giving money to people that assume that I'm a thief. Refusing to run if certain other processes are running - just for example, ones that track registry usage - is just nasty and suspicious; I could have been running Process Monitor for entirely innocent reasons.
