Mounting

3 of 4 done
  • Done

    Finds your copy

    Picks up the install on its own, from Steam or wherever it lives.

  • Done

    Reads every file

    Every file reads straight from your copy, in the order the game itself looks them up.

  • Done

    Matches players' copies

    Your copy is fingerprinted from its own files, so a server can check everyone's match without sending any game content.

  • Partial

    Brings its mods

    The two sample mods that ship with the game are found and fingerprinted, but stay off for now.

Converting

  • Done

    Models

    All 3,569 meshes. 110 props name a mesh the install lacks or ships only as a source file, and those don't convert.

  • Done

    Textures and materials

    All 1,973 materials, and 4,392 of the 4,408 textures they use. The other 16 are TGA files, which aren't read yet.

  • Partial

    Maps

    All 11, with their objects, props, spawn points and skies. Lights, decals, terrain, particles and sounds don't come across yet.

  • To do

    Models draw with their own textures, in ambient light only, through a stand-in shader until HPL3's own are rebuilt.

  • To do

    In the spawn menu

    Its props and models land in your spawn menu, no Plugin needed.

  • Done

    Maps you can visit

    Pick one of its maps from the menu and fly around inside it.

Where it stands

Evil Engine finds the Bunker on its own and reads it the way the game does. Its files point at each other by paths from its developers’ own machines, so most of the time the game falls back to finding a file by name across the folders its resources.cfg lists, and Evil Engine does the same. That’s a little under 23,500 files, fingerprinted in parts (the props, each of the 11 maps, the scripts, settings, sounds and voices), and every file matched Steam’s own checksums.

All 11 maps show up in the Singleplayer menu. Pick one and it converts with the game’s own models, materials and textures, and you fly around inside it with a free camera. The largest, the Central Bunker, places about 4,700 models and converts in about three and a half seconds. Where a map has a sky and a sun, those come across too. What’s missing for now is light: the maps’ own lights aren’t converted, so everything draws in flat ambient light.

Known issues

  • No lights yet, so maps look flat. Layered materials show only their first layer, and decals and see-through surfaces don’t draw quite right.
  • When two files share a name, which one the game really loads hasn’t been settled for 51 names. Both are kept until it is.
  • Rotations, which way you face when you spawn, and how skies are turned all come from the game’s files, but haven’t been checked against the game itself.

Next up

  • Settling which file the game loads when two share a name.
  • Checking rotations, spawn facing and skies against the game itself.
  • Lights, decals, terrain and particles, as Evil Engine’s formats for them land.
