Configuring Hammer++ for Half-Life: Source

Preparations

1. Install Hammer++ Source SDK Base 2013 Singleplayer to your Half-Life 2/bin directory AND DONT OPEN IT, IT WOULD LEAD TO BAD CONGFIG IF YOU CONFIGURE IT RIGHT NOW 2. Edit HL:S's gameinfo so in between of "hashdcontent 1" and "FileSystem" lines you have "GameData "halflifesource.fgd"" and "InstancePath "[SteamLibraryFolder]\steamapps\common\Half-Life 2\hl1\maps\mapsrc\instances"" It would look somthing like that:

Note:"GameData" is needed for instances to work(Also in regular Hammer).

Gameinfo.txt that is ready

Note:"InstancePath" is an absolete path to your instance folder.

Note:halflifesource.fgd must be placed into Half-Life 2/bin folder.
