SourceToSoF2 v1.1.1

Changelog

v1.1.1

Three fixes found by testing v1.1.0 on de_cbble.

Fixes

• Invisible Source volumes no longer cast shadows. A brush made of Source's
  nodraw is solid but invisible, and casts no shadow in Source - the compiled
  Source map has no faces for it at all. Converted, it blocked light and left
  hard black patches: on de_cbble a func_breakable over the long roof left a
  640 x 240 unit band of wall and trim pitch black where CS:S has it sunlit.
  Those volumes still stop players and bullets, they just let light through.
• Terrain in patch mode no longer shows the missing-texture grid. The
  terrain's shader name is built from the map's material, and the four names
  derived from it (_0, _1, _0to1, .vertex) ran past the 59 characters
  SoF2 allows, so the shader file shortened two of them while the .map kept
  the long ones and nothing matched. The name is shortened up front now, with
  room left for the suffixes. lwo terrain was never affected.

Editor

• Terrain shows its own ground texture in Radiant instead of the flat
  tools/_terrain tool texture, so a landscape is easier to edit by hand. The
  compile is unchanged.
• The slabs under displacement terrain draw solid in Radiant instead of
  see-through, so they are easier to pick and move.

Notes

• Reconvert the whole map (not the compile alone) after updating: the terrain
  names in the .map and in the .shader change together, and new alphamap
  .pcx files are written.

SourceToSoF2 v1.1.0

Changelog

v1.1.0

Lighting now matches the lighting Valve baked into the CS:S map. Measured
against Valve's own lightmaps, de_dust2 comes out at 1.00 in sunlight, shade
and lamp-lit areas (the B tunnels were at 0.57 in v1.0.0).

Lighting

• Texture lights. Rooms Source lights with glowing textures (fluorescent
  tubes, light panels, emergency lamps: lights.rad) instead of light entities
  are now lit. Those lights exist only in the map's compiled .bsp; the tool
  reads them from it, and the textures glow as they do in CS:S. On de_cbble
  the tube room went from black to 1.05 of CS:S.
• No more cut-off light. q3map2 throws away light below a fixed threshold,
  which cut every dim lamp off well before its light reached the floor. The
  converted map is now set up so this no longer happens, with no change to
  light that was already correct. The compile .bat passes the matching
  -brightness / -vertexscale / -gridscale values, worked out per map.
• Removed the flat ambient fill that stood in for the bounce light q3map2
  used to lose; with the bounce light arriving, it only made dark corners too
  bright.
• Lamps inside props (lanterns, light fixtures) light the room around them
  instead of being blocked by their own model, and their glass glows.
• Window frames and wall details on props were too bright and are back to
  normal.
• The quick test .bat now lights exactly like the full one (only
  visibility is faster), so test builds show the final lighting.

Fixes

• Windows, door frames and other props near the 3D skybox no longer
  disappear: the skybox area is found by the skybox's own brushes instead of a
  sphere around the sky camera.
• The gap in the terrain on de_cbble (and the void seen through it) is closed:
  terrain edges are no longer snapped to a neighbour that would move them
  sideways.

Notes

• Use NetRadiant's q3map2 (as before). It is needed for the new compile
  options; the .bat warns if the one you picked does not have them.
• Keep the map's own .bsp next to the .vmf (or under the content folder)
  so texture lights can be read. The GUI shows whether it was found.
• Compiles take longer than before (de_dust2: 484 s -> 666 s on 16 threads);
  big prop-heavy maps take longest in the bounce pass.
• Reconvert maps made with v1.0.0: the lights in the .map and the compile
  options in the .bat change together.

v1.0.0

First release.

SourceToSoF2 v1.0.0

First public build. Converts Source engine maps (.vmf) into Soldier of
Fortune II: Double Helix multiplayer maps — brushwork, displacement terrain,
props, decals and overlays, textures, shaders, collision, lighting, the 3D
skybox and the map's own ambient sounds. One window, ten steps, one button.

Tested on CS:S and CS:GO maps decompiled to .vmf (de_dust2, de_cache,
de_overpass, de_mirage, de_cbble) against SoF2 MP 1.03.

Download

SourceToSoF2.exe below is the whole tool — it carries its own Python, so
nothing else needs installing.

You also need

• A 64-bit NetRadiant q3map2. This matters: other builds (GtkRadiant 1.6.7
  ships one) keep the .bsp draw lumps in fixed arrays and stop with
  MAX_MAP_DRAW_INDEXES part way through -bsp, and a 32-bit q3map2 fails in
  -light with safe_malloc failed on allocation. The tool checks the
  q3map2.exe you pick and warns before it runs. Editing in whichever Radiant
  you prefer is fine — this is only about the build that compiles.
• Your Counter-Strike: Source content, and a SoF2 install with its base folder.
• The map as a .vmf. For a map you only have as .bsp, decompile it with
  BSPSource first.

Before you play

Set com_hunkMegs 256. SoF2 loads the whole .bsp as one block inside the
2 GB a 32-bit game can use, and a large hunk such as 1024 reserves half of
that at startup — a big map then fails with Z_Malloc(): Failed to malloc.

Known limitations

• Props: maps built mostly from props (de_cbble) cannot keep every prop at
  full detail inside SoF2's limits. Expect simplified props and missing small
  clutter; the step 6 log lists exactly what changed.
• Prop skins: a prop placed with a skin other than the first is converted
  with skin 0 — mostly visible on foliage and light fixtures.
• Game logic: Source's entity I/O, bomb sites and buy zones are not converted.
• Sounds: the map's own CS soundscapes, as SoF2 speakers, capped at 32.

Reporting problems

Open an issue with the map, what you saw (a screenshot and the in-game
viewpos help a lot), and the SourceToSoF2.txt log written next to the .exe.
Add the compile window's output if it was the compile that failed.
