I noticed from Mr Erps vid tut that, when he says " Now lets enter some models to blow up" that they are script models and NOT just models....so check them m8y ;)

I ran fast VIS after the compile, it worked, it finished, and the size of the bsp increased, only It didn't fix the bullethole/granade/bombs thing, made a new topic about that one..

When you test your map, is the player all shadowed or can you see your arm and guns normally, as you may not have the world spawn values entered correctly and this could effect the way you see things in open areas of your map as they won't be lit correctly. You won't see bullets holes and stuff ;)

I did have that before but I fixed that one, there seems to be a bug in cod radiant as it didn't let me create the worldspawn, (i've done it manually). and the ambient etc works now..
