Smooth Motion Blur

# Smooth Motion Blur **Velocity-based motion blur that makes your gameplay look buttery smooth.** This mod recreates the way fast motion looks to the human eye: instead of uniformly blurring the whole screen, it reconstructs the *direction of camera movement* for every pixel and smears only along that path. Fast flicks produce clean directional streaks, the center of your view stays sharp, and the moment you stop moving the image is instantly crisp again — no smeary afterimages. Perfect for PvP clips, montages and cinematic recordings. It is recommended to start with a strength of **80**. ## Features * **Velocity-Based Blur** — per-pixel reprojection using the depth buffer and previous-frame camera matrices * **Sharp where it matters** — first-person hand, HUD, menus and screen center stay crisp * **Strength Command** — `/motionblur 0` to `/motionblur 300` * `0` — off * `1–100` — natural range (streaks match your real camera motion) * `101–300` — overdrive for extra-long cinematic streaks * **Hotkeys** — `[` and `]` fine-tune the strength in 5% steps (rebindable) * **Adaptive Quality** — sample count scales with streak length, so long streaks stay smooth without wasting FPS on small motions * **Instant Response** — no accumulation ghosting; blur reacts to every single frame * **VulkanMod Compatible** — built entirely on the vanilla GpuDevice render abstraction, no raw OpenGL calls * **Client-side only** — works on any server ## Commands | Command | Effect | |---|---| | `/motionblur` | Show current status | | `/motionblur 0` | Disable | | `/motionblur 1-300` | Enable + set strength | Settings are saved to `config/motionblur.json`. ## Compatibility * **Minecraft:** 1.21.11 (Fabric) * **Requires:** Fabric Loader ≥ 0.16, Fabric API * **Works with:** VulkanMod, Sodium ## Credits & License The velocity-reprojection blur technique is adapted from [**Natural Motion Blur**](https://modrinth.com/mod/natural-motion-blur) by **ItsPasi** — huge thanks for open-sourcing it!
