the leak source engine

[clayton0127]

ok, so you guys know how the engine was half goldsrc half source? well, if i take a map from half life 1, and put it in leak half life 2, will the textures be there? because someone said some of the maps were made for goldsrc.

the engine is different. map won't load.

That's a pretty popular myth. The truth is - technically HL2 was never on GoldSrc, it started it's development on a different branch called "Src" that eventually got well-known name - Source.
Proof can be found here.

Of course in the begining, around 1999-2001, the engine looked much like GoldSrc but anyway, it already had many differences, like physics for example.
And no, you can't run HL1 maps on 2003 leaked version of it. HL1 textures won't work too.

You should use Xash3D if you want better textures in GoldSrc games.
