A bit of a surprise
to see a dedicated forum given the age of the engine, but it's neat to see it
here.
Unless
you're authoring hats/swords/stickers, Source has a notoriously hard pipeline
that hasn't aged well. Despite that, it's still pretty popular for mods, machinima,
and even indie games that usually started out as mods.
Its
strength in source is the community behind it, though - everything I've ever
learned about the source engine pipeline came from reading the Valve Developer
Community,
or asking on forums. Since there's a source section now, I suppose it'd be good
to have a general Q&A thread.
To
start, here's some helpful links for (old school) source content
authoring/modding:
Interlopers
Tutorials (mapping/general
tutorials)
VIDE (Mapping tools)
Nem's Tools (texture tools/gcf
extraction)
Notepad++ and N++ Extensions (valve language text
file editing)
Crowbar (model decompiling)
Wallworm Model Tools (modern tools for
3dsMax)
