Develop mods for Black Mesa

I wondered today whether it’s possible to develop mods for Black Mesa with the Source SDK. I don’t own half life, I just have Black Mesa and the Source SDK 2007 installed. There are some Threads on this topic, but they describe how to use for example Hammer Editor with Black Mesa, but they all use the half life 2 directory in the Game Configuration! Hope you can help me!

You’ll need to install the Source SDK 2013 Base 2013, and configure it for us w/ Black Mesa. One of the members here created a small tool to make setup a breeze, which you can get here.

Do I really need 2013? My Black Mesa works without SourceSDK Base 2013

Yes. Black Mesa runs on the 2007 base, but the tools that work with it (after some general updates by Valve) are in the 2013 Base.

Thanks man! That works. Finally I can start creating maps, after a thousand of abortive attempts…

Goodluck! Make sure to show off what you make, I’m sure loads of people here would be interested.

What that guy said! Leak-Free is too damn slow.

Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
