NDVDB

Cinematic OpenVDB importer & real-time renderer

Import and play your own OpenVDB sequences as real-time lit volumetrics: smoke, fire and explosions that composite correctly with each other, your scene and your water.

• ▦Joint compositing. Every visible volume raymarched in one pass, with correct overlap and cross-volume shadows.
• ✺Lighting & fire. Self-shadowing, scene shadows, point and spot lights, and fire that lights its own smoke.
• ≈Water. Wave-accurate splits at the rendered surface; KWS2 and Crest detected automatically.
• ⏱Timeline. A native track for sequencing multi-effect shots.

The Arcade

Three games, one cabinet, nothing to install

ADRIFT (prototype v16.49): a space-horror roguelite lit by one failing flashlight — solo, couch co-op, or online by room code. Jet Slalom and Area Flat 3: faithful remakes of two Flash-era MR-C classics, rebuilt from scratch for the modern browser with crisp or crunchy rendering, gamepad and touch.

ADRIFT: created with Claude Code, design by James Carroll & Michael Arens; a prototype toward a Discord game. Jet Slalom and Area Flat 3: remakes of the MR-C originals.

• ◐ADRIFT. Wake from cryo aboard a ship that rearranges itself every sleep. Four sectors, three power cells each, a shadow-cast beam, and the dead going for whoever is nearest.
• ▲Jet Slalom (remake). Skim the deck through procedurally grown pyramid fields, chicanes, spire storms and canyon runs — always with a way through. Classic or Relaxed pace.
• ✈Area Flat 3 (remake). A vertical shooter across eight shifting landscapes with weapons that grow into something else, and five bosses. A thumb-controlled build for phones.
• ▦The cabinet. Crisp re-renders at your display's true pixel density; Crunchy keeps the fat pixels. Settings apply mid-run; Esc returns to the arcade.

Roadmap

What is coming to NDVDB after 1.0, in priority order. The first two are in testing now and will be released as soon as the Unity Asset Store approves the update; the rest are planned.

• In testing

  Converting on macOS and Linux

  Converted assets already play on Windows, Linux and macOS, but today the converter itself runs in the Unity Editor on Windows x64. The OpenVDB reader is being built natively for macOS (Apple Silicon and Intel) and Linux x86_64, so a whole team can import sequences on the machines they already use.

  Every build is checked against the Windows converter: the same sequence has to produce the same data on all three.

• In testing

  32 volumes composited at once

  The compositor currently marches up to eight volumes jointly in view; past that, extra effects still render, but without joint overlap or cross-volume lighting. A scene-wide brick pool removes the per-shader texture limit behind that ceiling, and the update raises it to 32.

  Cost follows what is on screen, not how many effects exist: each ray marches only the volumes it actually crosses, and cross-volume shadows test only the volumes that can stand between a volume and each light. The shared pool also keeps GPU memory to the bricks in use, and brings the compositor to OpenGL Core.

• Planned

  Liquid VDB sequences

  NDVDB imports density volumes today: smoke, fire and explosions. Liquid simulations are exported differently, as an animated surface (a level set) rather than a density field, so they need their own import path and their own way to render.

  This adds both: animated liquid VDBs from Houdini, Blender and other DCCs, played back in real time and lit alongside your smoke, fire and water.

• Planned

  Real-time FX

  Everything NDVDB plays today is simulated ahead of time in your DCC and streamed back. Real-time FX adds effects that run live in the engine, with parameters you can change while the game is running, so an effect can react to gameplay instead of replaying the same way every time.

• Planned

  FX Director

  NDVDB plays from a native Timeline track today, but not every team sequences in Timeline. The FX Director adds NDVDB's own stack for directing a shot: cue effects, time-remap and layer them, and set their look from one place, with or without Timeline and alongside the cinematic tools you already use.

  Designed to be easy to pick up from the start, for artists as much as programmers.
