    Impressive, given how old Q1 engine is. It brings back memories of Paranoid Doom mod: https://www.doomworld.com/idgames/levels/doom2/Ports/p-r/par...

    Interesing, there's more here including HL1 (a.k.a "valve")

    Funnily enough the looks of this HL2 through this engine makes it flow more with HL1 than I could expect; an interesting reverse Half Life: Source / Black Mesa / demake of sorts.

      Even simple Half-Life 1 mods built on textures and models from Half-Life 2 look much closer to 2 than one would expect. For example this mod, but not only:

      You won't confuse it with modern Half-Life 2, but the original HL2 engine had far worse graphics than the latest version. Makes you realize how much of the difference between HL2 and HL1 is due to different textures and level design.

        And Viktor Antonov (rip) art style.

        edit: there is also the fact that map compilers for gold source games have advanced far beyond what they could do back in 1999. The lightmaps and light sources alone can be far more intricate nowadays than what you would get from the official valve ones in 1999.

    FTE barely qualifies as a pure Quake engine at this point though, it does tons of stuff.
    • vkazanov2 hours ago
      It does a lot, yes, but also is very much a continuation of the original codebase - i've spent quite some time tinkering with internals of it.
      • jsheard2 hours ago
        Yeah, but Half Life 2's Source engine was itself a continuation of Goldsrc which was itself a continuation of the Quake 1 engine. The lineage is there but beyond a certain point it's not really Quake anymore.

        GZDoom/UZDoom is a similar grey area, it is built on the original Doom codebase but they've added so many features that it's practically its own distinct engine now. Those forks can even render arbitrary 3D models, which OG idTech couldn't do until Quake.

        • vkazanov2 hours ago
          We'd have to come up with definition of quake :-) FTE has a lot bolted on it but the focus us in Quake, quake mods, lifting some limitations and making mod dev convenient.

          But it is the same overall code structure, the same game, etc.

          All these oss quake engines, are they quake? Ironwail, quakespasm vkQuake?

            I think the litmus test is weather they are backwards compatible with old maps/campaigns from the original engine/game.

            Half-Life 2 sure won't play quake maps nor will it play hl1 maps.

    Half-Life 2 looks incredible in Quake 1, what gives?

    Seems to be using a dnsft.cloud.zyxel.com certificate. Is this a home router?

    • linuxguy219 minutes ago
      I certainly don't get that cert. I'm seeing a LetsEncrypt cert for idtech.space with various SANs.

        # host code.idtech.space
  code.idtech.space is an alias for idtech.space.
