Just be wary that you'll need to pack the .raw files I used for the colour correction into the bsp because the workshop uploader for garry'smod blacklists .raw files

I know the map seems small but it actually takes up a pretty significant portion of the hammer grid, so keep that in mind while building.

It's also a little heavy on the in-editor compiler so I lightened the load and increased stability a bit by using VBCT

and for your own reference I used the -staticproppolys and -staticproplighting flags for vrad so that the tree shadows show up properly (forces lighting calculation based on visible model rather than the collision mesh)

Oh, and uh, I'm pretty sure I was in the middle of trying to fix the sound setup last time I stopped working on it, so you'll probably find that a lot of the ambient_generic entities I used to loop various effects are missing. They were causing audio problems anyway, so I hope it's not too big a nuisance that you'll have to set up your own ambiance
