On occasion I convert some of the maps on Garry's Mod to a BSP to see if they are compatible with SFM and look decent enough. This Definitely would fall under that category and better. Here is the preview on Garry's Mod Workshop LINK As far as credits go it says it was created by Loadingue and Catfood on the Workshop page. IMPORTANT When you load up the map make sure you enter the following into the console to eliminate the white splotches on the map mat_specular 0 and that should clear up any problems. As always if there is an issue with the upload please let me know.
