1.9.52

LatestOct 14, 2026

New

  • Canvas warps: perspective and mesh warps for curves and fixtures, with corner pins, soft-falloff mesh points and a Warps list in the sidebar.
  • 22 more blend modes, and per-layer clip transitions with a blend mode and optional duration.
  • Fixture channel routing: every channel names its source (Color, Aux 1, Aux 2, a fixed value or a 16-bit fine byte), fixtures can carry head channels such as a master dimmer or strobe, and the fixture editor offers built-in profiles for common strips and pars.
  • Per-Surface colour calibration with RGB gains and white balance, and a WLED-style current limiter with a live draw meter. Fixture gamma is now applied to output.
  • Surface brightness and colour faders are MIDI, DMX, OSC and modulation targets.
  • Crop effect: rectangle or ellipse insets with feather, rounded corners and invert.

Improved

  • A major performance pass across the app: previews run judder-free, fader, knob and envelope interactions no longer stall them, and large projects stay snappy when dragging on the canvas, editing shaders or working with long sidebar lists.
  • The status bar warns when macOS Low Power Mode or thermal throttling caps previews at 30 fps.
  • Output windows on show displays cover the menu bar, hide the cursor and follow every Space, and the machine stays awake while any output is live.
  • Clicking an empty grid cell stops its layer.
  • Filament reopens on the page it was closed on.
  • Ember Rain covers the whole canvas and fades embers in and out.

Fixed

  • Previews could drop a frame whenever two arrived together, which showed as judder at a steady frame rate.
  • Opening a project could leave the clip grid empty until the next edit.
  • Dragging a beat-rate slider no longer drops the row's Sync mode.
  • The shader editor preview and the effect test card keep the project's aspect ratio.
  • The mask toolbar's Shapes and Edge blend panels open fully instead of being clipped by the toolbar.

1.9.49

Oct 9, 2026

Improved

  • Windows: previews are smoother, Spout input and hardware video decoding are faster, and the monitor list updates when a projector is plugged in.
  • Smoother video playback, timeline editing and canvas editing in large projects.
  • External inputs that aren't on air use far less processing.
  • Audio outputs on separate devices stay in sync over long shows.
  • Windows downloads are now a single .exe installer.

Fixed

  • If the library can't be opened at startup, Filament offers to restore a backup or start fresh instead of failing to launch.
  • LED output could occasionally repeat a frame.
  • Some 10-bit and 4:2:2 videos played incorrectly with hardware decoding, and some files had the wrong duration or start time.
  • Colour and transparency fixes on outputs.
  • Drags that ended outside the window could get stuck.
  • Opening a project kept the previous project's timeline zoom and selection.
  • Video recordings no longer overwrite earlier takes.
  • Audio input recovers better after a device error.
  • OSC now sends feedback for group opacity and group effects.

1.9.48

Sep 21, 2026

New

  • Standalone player: a small companion app that replays a DMX show exported from the composition timeline straight to your fixtures over Art-Net or sACN, with no Filament and no computer needed. It runs on Raspberry Pi, macOS, Windows, and Linux.

Improved

  • Timeline video exports now use the composition canvas size instead of a fixed resolution.
  • Single fixtures multi-edit bugs fixed.

1.9.47

Sep 21, 2026

New

  • Standalone player: a small companion app that replays a DMX show exported from the composition timeline straight to your fixtures over Art-Net or sACN, with no Filament and no computer needed. It runs on Raspberry Pi, macOS, Windows, and Linux.

Improved

  • Timeline video exports now use the composition canvas size instead of a fixed resolution.

1.9.46

Sep 8, 2026

New

  • Art-Net input: Lighting consoles can now drive Filament over Art-Net DMX: launch clips, select a layer's clip from a single fader, and ride any parameter from console channels — with DMX Learn, manual universe/channel entry, a live DMX monitor, and Filament appearing by name in console patch windows.
  • MIDI output: Controllers now follow Filament — pad and button LEDs mirror clip and toggle state, motorized faders and encoder rings track parameters, Launchpad and APC grids mirror the clip grid as a movable session ring, Mackie Control surfaces work with zero setup, and Filament can send MIDI clock. Pitch-bend and 14-bit MIDI input are supported too.
  • Linux users can now install Filament with `.deb` and `.rpm` packages.

Improved

  • Launching a clip now keeps the outgoing content on screen until the incoming clip has its first frame ready, instead of cutting to black while it loads.
  • Add Layer now inserts the new layer directly above the selected layer and inside its group.
  • OSC input can now be limited to an allowlist of sender addresses.
  • Follow-playhead and cue-list visibility now save with the project.
  • macOS now asks for Local Network permission on first launch so Art-Net, sACN, NDI, and OSC traffic isn't silently blocked. macOS 13 or later is now the stated minimum, matching what the bundled libraries already required.
  • Project saves, switching, exports, backups, and crash recovery now protect your work more reliably if an operation is interrupted or a file is damaged.
  • Video, images, previews, and live inputs now run more smoothly, with more consistent transparency and reverse playback.
  • Custom media folders, relinking, thumbnails, and waveforms now recover more reliably when files or storage locations are unavailable.
  • Library and fixture exports now better protect existing files and handle conflicting filenames safely.

Fixed

  • Arrangement clips no longer resume at the wrong position, or with silent audio, after switching back from Session view.
  • Clip and Layer previews now show the layer the timeline is playing while in Arrangement view.
  • The macOS video engine no longer clashes with NewTek's NDI HX driver over shared capture classes.
  • Duplicated and imported projects no longer share Surface mappings with the original project.
  • Fixed some crashes and freezes affecting rendering, playback, imports, and unresponsive windows.
  • Multiple cells using the same media file now keep their own playback settings and progress.
  • Duplicating a Surface no longer risks assigning lighting addresses that are already in use.
  • Older Filament versions no longer risk changing libraries created by newer versions.

1.9.45

Aug 18, 2026

Fixed

  • The Windows build of 1.9.44 failed and never shipped, so this release delivers those changes to Windows: DirectX 12 rendering, Spout format support and stability, and the video-playback crash fixes. Nothing new on macOS and Linux.

1.9.44

Aug 18, 2026

Improved

  • Windows DirectX 12 & Spout hardware video decode improvements
  • Spout stability improvements
  • Overly verbose debug logs stfued on production builds

Fixed

  • Playing a video clip could crash the player runtime over and over on Windows machines where the renderer had ended up on Vulkan
  • Choosing Resume from the tray icon on Windows removed the icon but never brought the window back, leaving the app unreachable. Resume now restores the window reliably.
  • Spout senders publishing float (fp16/fp32) or 10-bit color displayed as garbled colors. They now render correctly.
  • Numeric fields UI tweaks

1.9.43

Aug 16, 2026

Improved

  • On exit, Filament now tells sACN receivers it is done with their universes, so they release the output immediately instead of waiting out a signal-loss timeout.
  • If the crash-recovery notice appears, it now names the exact source location of the fault, making reports much easier to act on.
  • Sending a bug report is more resilient: if part of the diagnostics snapshot can't be collected, the report is sent anyway with a note about what's missing, and larger reports get more time to upload on slow connections.

Fixed

  • Launching Filament while it was already running (including minimized to the tray/menu bar) started a second copy that kept sending its own DMX output — receivers saw two senders on the same universes and the LEDs flickered between live frames and black. Opening the app again now brings the running copy to the front instead.

1.9.42

Aug 15, 2026

Fixed

  • Windows DMX output fixes.
  • Art-Net node discovery on Windows now also polls each connected network's broadcast address, so it can find nodes that don't answer the global broadcast.

1.9.41

Aug 14, 2026

Fixed

  • Fix waveform/export audio truncation for large-packet codecs

1.9.40

Aug 13, 2026

New

  • Universe boundaries setting on Surfaces: choose whether pixel channels split across universe boundaries or pixels stay whole per universe. Replaces the per-curve "avoid universe boundary split" option
  • Timeline clip envelopes can cycle: once over the clip as before, locked to the beat grid so moving or trimming the clip never shifts the pattern against the music, or at a fixed length in seconds
  • Timeline animation clips now have a palette picker in the inspector
  • Performance capture options: trim leading silence, capture as a new arrangement instead of appending, and a per-control record arm in the control's right-click menu
  • Simplify button on automation lanes thins dense captured curves down to their corners while keeping hand-placed and eased points
  • Group opacity and volume can be automated with timeline lanes
  • Animations and external sources can be auditioned in the preview pane via their context menu, not just video files
  • Video clips on the timeline draw their soundtrack's waveform under the filmstrip, following trims, slips and loops
  • Exported videos now include the audio of video clips, matching the live mix — volume, mute/solo and fades/crossfades sound like they look

Improved

  • F2 renames the selected session column
  • Loading a library tile with no cell selected drops it into the next empty cell (adding a column if needed) instead of asking for a selection
  • Media check now also flags timeline clips whose files are missing, and the clip inspector shows a warning for them
  • Removed the external input timeout setting, which had no effect — per-cell inputs black out on connection loss by design

Fixed

  • A slow project load at startup could sometimes permanently wipe the project's clip grid and timeline; the race is fixed, and any save that would empty a populated project is backed up first
  • The grid's palette switcher no longer silently changes a hidden grid cell while a timeline clip owns the panel
  • Copying, pasting or dragging an effect between chains keeps its modulation bindings instead of dropping them
  • Video soundtracks decode in full — long videos previously lost their audio tail in waveforms and exports

1.9.37

Aug 7, 2026

New

  • Timeline minimap with a wheel-style map overlay and collapsible group bands for navigating big arrangements
  • Video clips on the timeline show filmstrips, and animation clips show their artwork with aspect-correct thumbnails
  • Timeline clips have their own effect chains, editable in the inspector
  • Drag a clip from the grid onto the timeline toggle to drop it on the timeline at the playhead
  • Beat-sync picker on animation and effect rate parameters — pick musical divisions instead of typing raw speeds
  • Envelope segments can be bent into smooth curves by dragging, and adding a point flows straight into a drag
  • Refresh-thumbnail action on timeline animation clips, and thumbnails now include the clip's effects
  • Connections page lists keyboard triggers and groups saved connections by type

Improved

  • Settings reorganized into compact grouped sections, with software updates at the top
  • Previews keep updating smoothly even while the rest of the interface is busy
  • Dragging knobs and faders is smoother on large projects
  • The edge-detect effect now finds edges also in transparency, not just brightness (selectable)

Fixed

  • Clip audio no longer cuts off near the end of clips or drops out after playback hiccups and loop seams
  • Radial blur no longer shows ghosting artifacts at its outer rim
  • Detached preview windows open at the content's aspect ratio instead of a stale size
  • Envelope preset gallery and modulation indicators no longer overflow or widen the parameter pane
  • Panels no longer close while scrolling their own content
  • Failed audio outputs retry calmly in the background instead of flooding the log
  • Video-only rigs pass the output preflight check without needing LED surfaces
  • Palette files can be dropped with any file-extension casing, with a prompt before replacing an existing palette
  • The footer's CPU and memory readout counts the whole app, not just the main process

1.9.35

Aug 5, 2026

New

  • Release-notes system — notes files, publish script, CI wiring

Fixed

  • Fixed Linux GPU startup being disabled by the app's own environment settings

1.9.34

Aug 5, 2026

New

  • Projects now keep versioned document backups, so an interrupted save can be salvaged instead of lost

Fixed

  • Opening or closing a detached preview window no longer freezes the app on Windows
