All you have to do is compile it with HDR lighting, and pack any custom materials/models/etc in it. Don't compress (repack) it, SFM still doesn't support the newer BSP maps and it'll crash if you want to open a compressed map (if you want to use repacked maps in SFM, use
this to unpack them). Then all you have to do is find the TF folder inside the Source Filmmaker folder, drag your map into the maps folder and boom, done.
