After weeks of work, I quit!! I spent 77 hours on my first map. An awsome map!! It was so cool... And what happenned? I lost all the lights and sounds!!! And today it was the 3rd time I was making a complex ufo! I already lost around 30 hours of work. The lights is around 20 hours. I am tired of loosing stuff! I appreciate all the help given to me on this forum. I had many troubles in my map and this awsome community helped me solve the problems. I can't keep making the map... because the freaking source sdk deletes it!!!!!!!!! Bye!
