• Welcome!

    Welcome to Source Modding where you can learn how to use Valve's Source SDK or Half-Life SDK to modify the stock games or even create your own.

    You will find a wealth of useful information here, everything from in-depth tutorials from either myself or the ever generous Source Modding Community, to tools, community links and history regarding everything Valve related.

    The website and tutorials are an ongoing project of mine and i hope to keep them available to you as long as possible.

    Let me know via E-Mail if you have any suggestions, requests or ideas for improvements. Or Simply submit a Link here.

    The website is under active development, expect non critical bugs, half finished pages and some weird stuff here and there,

    I have just finished the Tools section and can now turn my attention to collecting tutorials from the community and creating my own.

    Thank you for visiting sourcemodding, I hope you find the service useful.
    Kind Regards

    Cathal McNally
