Metrixel 2026.2.1 — Linux goes GA, plus precise animation frame control

Metrixel 2026.2.1 graduates Linux from Preview to general availability — it's now a fully supported, production-recommended platform on equal footing with macOS and Windows. This release also lands a complete animation frame-control toolkit so you render exactly the frames your dataset needs — nothing more.

If you're generating training data from animated assets, this one cuts wasted renders, disk, and time.

What's new

Linux is now generally available

In 2026.2.0 we shipped Linux as a Preview for early-adopter 3D-ML teams. After a release cycle of feedback from people running Metrixel on Linux training hosts, Linux is now a general-availability platform — supported and recommended for production pipelines, alongside macOS and Windows.

• Native Vulkan on discrete NVIDIA GPUs — SDF generation and rendering run at full bandwidth, noticeably faster than Apple Silicon for large volumes.
• One relocatable tarball (Metrixel-2026.2.1-linux-x64.tar.gz.zip) covering Ubuntu 24.04 and Red Hat Enterprise Linux 9 (x86_64). The tarball bundles EntVista Hub, so one download installs both — extract anywhere, run ./install.sh, done.
• Headless / unattended install for Amazon SageMaker jobs, CI runners, and SSH-only hosts (QT_QPA_PLATFORM=offscreen), the same as macOS and Windows.

macOS and Windows continue exactly as before; the change is that all three platforms now carry the same supported, production-recommended status.

Total control over animation frames

Building training datasets from animated assets used to mean rendering a full, fixed-rate timeline and discarding most of it. 2026.2.1 gives you exact, predictable control over which frames render — in both the GUI and the CLI:

• Frame-range selection. Render a specific span with --frame_range=START:END (or the new GUI controls) and capture just the frames you care about.
• Frame subsampling. --frame_stride=N renders every Nth frame, thinning a dense animation into a representative sample.
• True low-rate sampling. The --frames_per_second floor drops from 24 to 1, and fps is now actually applied in the render loop. A 1-fps pass over a 4-second clip yields ~4 frames instead of a fixed full-rate timeline — frame count finally scales with the fps you ask for.
• Smarter defaults for static models. Assets with no animation now render one frame per camera angle instead of a phantom multi-second timeline — a large cut in output size and render time for static meshes.

Together these make the old "trim every asset to a single keyframe" workaround unnecessary: you dial in exactly the frames you want at the source.

Fixes

• No more dropped first frame. Fixed an off-by-one where the last camera angle's first animation-frame image was missing from the output.
• Cleaner settings panel. Collapsible sections in the GUI no longer show a redundant inner scrollbar when there's room to expand.

Known limitations

• SDF export remains a Professional-plan feature. Free and Standard accounts see the option, but the export is skipped at runtime with a subscription message.
• Imports beyond 200 MB are still skipped to keep processing predictable — we're raising this limit in a follow-up release.
• On Linux, GA ships as the relocatable tarball — that is the distribution format, with no separate native-package or installer step.

Pricing

No tier changes. The new frame-control options are available across the processing modes you already use; SDF export stays on the Professional plan alongside batch mode, TIFF export, and USD animation export.
