New fence

I've changed the perimetral fence of map three. At first I just used some fence texture that was included in the left 4 dead 2 sdk, but now I made a new fence that's more like the real one.

Here you can see the real fence from a Google Street View capture.

To make it, first step was drawing a 3d model of the fence in Hammer:

Then, I captured the image of the 3d view window, edited it to create an alpha channel, and then converted it into a texture file wih VTFEdit:

And, finally, I added the columns and the top beam to complete it:

But it was not easy, and I had to pay a price to accomplish this change. I had to turn some func_details into func_brushes, and increase the lightmap of the whole map from 16 to 18. This way I keep my waterindices under 100% and prevent vrad from crashing when compiling with hdr. Bad side is that now shadows and reflexions will be more diffused, but I think that this new fence worths it.
