First release of d_ren, a Vulkan renderer for LithTech 1 that replaces Blood II's d3d.ren / soft.ren.

Blood II rendered by d_ren

Install

  1. Unzip d_ren-0.1.zip into the Blood II folder (next to CLIENT.EXE). It contains a single d_ren.ren and a readme.
  2. In the game's launcher, open the display settings and pick the d_ren renderer and a resolution.

The 3D view renders at your monitor's full resolution, borderless fullscreen. The resolution you pick only sets the size of the menus and HUD.

Requires a graphics card with Vulkan support.

Highlights

  • Everything Blood II draws:
    • the world with lightmaps;
    • animated characters and weapons;
    • doors and lifts;
    • sprites, particles, water and the sky;
    • fog, screen flashes, model shadows and scrolling textures;
    • menus and HUD.
  • Checked against the original: behaviour is ported from a reconstruction of the original d3d.ren and compared against it running under dgVoodoo2.
  • High resolutions, widescreen and high frame rates. For example 4K at 240 fps, with a proper widescreen field of view.
  • Two fixes for engine problems at high frame rates, both done in memory with nothing changed on disk:
    • Above 100 fps the game normally runs too fast; at 240 fps physics, AI and cutscenes run at 2.4× speed. d_GameSpeedFix, on by default, keeps the game at normal speed.
    • Above ~64 fps, mouse look updates in uneven steps. d_MouseFix, on by default, makes it follow the mouse every frame.
  • Options are console variables saved in autoexec.cfg: d_VSync, d_MaxFPS, d_Widescreen, d_FogMode and the two fixes. They're described in the included readme.

Known limitations

  • Not yet done:
    • chrome (environment-mapped) models;
    • per-texel dynamic lights on lightmapped walls (they're approximated);
    • moving cloud shadows outdoors;
    • model detail levels;
    • the game's screenshot key.
  • The sky, water and line-system effects are implemented but haven't been checked against the original in every level.

Recommended, separate projects

  • dinputto8, if Blood II crashes at startup on current Windows (a DirectInput problem unrelated to the renderer).
  • A Blood II widescreen patch, for 16:9 menus and loading screens.

Reporting problems

Attach vk_test.txt and test.txt from the game folder. They're rewritten at every start.
